We have a web application built with target framework as x86.
On Server 2008 (IIS 7/7.5) we are able to run the application without any issue (For 64 bit system we enable 32 bit application from app pool).
On 32 bit server 2003 - no issue.
On 64 bit server 2003 (SP2) - we are unable to load a dll:
Could not load file or assembly 'acPDFCreatorLib.Net' or one of its dependencies. An attempt was made to load a program with an incorrect format.
We know this error comes on 64 bit system when Enable 32bit application is set to false. So I tried the following:
Ran the script:
cscript %SYSTEMDRIVE%\inetpub\adminscripts\adsutil.vbs SET W3SVC/AppPools/Enable32bitAppOnWin64 1
The issue persisted.
%SYSTEMROOT%\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis.exe -ir
On running this the World Wide Web Publishing service stops.
On trying to restart we are getting the following error
ISAPI Filter 'C:\WINDOWS\microsoft.net\Framework\v2.0.50727\aspnet_filter.dll' could not be loaded due to a configuration problem. The current configuration only supports loading images built for a AMD64 processor architecture.
Any ideas?
Below worked for me regarding the issue "Could not load file or assembly 'acPDFCreatorLib.Net' or one of its dependencies. An attempt was made to load a program with an incorrect format."
Go to Application Pools => Select the AppPool you have created (Else Choose DefaultAppPool or ASP .Net v4.0)
Right click AppPool and Select Advanced Settings
Set Enable 32-bit Applications to True
Reset IIS and Check
The following fixed the issue for me:-
Right Click "Web Sites" and select property
Go to Services tab.
Uncheck - "Run WWW services in IIS 5.0 isolation mode".
After removing the selection from Run WWW Services...., I was able to start the service.

Hi we have configured IIS with helicon and webgate.
when I am accessing my site I am finding Following Error message on page
HTTP Error 500.0 - Internal Server Error
Calling LoadLibraryEx on ISAPI filter "C:\Appl\Softwares\Webgate\access\oblix\apps\webgate\bin\webgate.dll" failedror
Please help.
My configuration as my other environment where all the things are working.
Yesterday, while setting up a website on IIS 7 and Windows Server 2008, I loaded up the website in the browser and ended up getting the following error message:
Calling LoadLibraryEx on ISAPI filter C:\…isapi.dll failed
The path was to the isapi.dll file in C:\Program Files\etc and I was pretty sure everything was setup properly. After doing a bit of research on the topic, I figured out that since I’m running IIS 7 on a 64-bit version of Windows Server and my web application was 32-bit, I had to change a setting in the IIS configuration.
To fix this problem, all you have to do is open IIS7 and click on Application Pools.
Then right-click on the application pool for your website or the default application pool and go to the Advanced Settings tab. Make sure that Enable 32-bit applications is set to True.
That’s it! Now restart IIS and load up Internet Explorer again and your website should load fine.
I received the same error after installing .NET 1.1.
After uninstalling .NET 1.1 I still had the same error.
However, the error has gone immediately after I went to IIS Manager -> ISAPI filters and removed the only filter from here (it was ASP.NET_4.0.30319.0).
This error might be because of the following reasons. Those are:
webgate installation folder has restricted permissions. Give required permissions for the webgate installation and configuration folder for the IIS process which runs your website. (Had you run configuration script for webgate or just manually configured it?)
There may be other DLLs missing on which webgate is dependent. For example, VC++ runtime redistributables. (For 10g use 2005 version, for 11g use 2012 version).
Some internal files are missing for webgate. Try re-installing webgate and running config script.
I have referenced some 32 bit and some 64 bit DLL in my ASP.NET MVC 3 project.
The projects compile but I get runtime errors.
It's because I am running the web project as 64 bit.
How do I "enable 32 bit" in my local IIS (just how I can do it in IIS 7.5 Pro)?
I am using .NET 4.0
The error I get is:
Retrieving the COM class factory for component with CLSID {A6775dfd2-1dfF-421C-A187-4D55F4DDFBFF} failed due to the following error: 80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)).
If you don't require the 64 bit component (not sure what is running there or if this can be excluded as you simply wanted to know how to run in 32 bit more)
http://learn.iis.net/page.aspx/201/32-bit-mode-worker-processes/
You can set it at the server level via:
%windir%\system32\inetsrv\appcmd set config -section:applicationPools -applicationPoolDefaults.enable32BitAppOnWin64:true
Or set your particular app pool (more recommended imho) you can try the following. Sorry the page this came from is no longer seemingly active and only googles caches is showing it now:
Force IIS to create a 32-bit app pool worker process
If your application is running as a web app, meaning it is running in
an IIS app pool worker process, you’ll want that worker process
(w3wp.exe) to be a 32-bit process. That can be specified in the
advanced settings of the app pool:
Select the app pool for your web app. Click Advanced Settings… under
Edit Application Pool on the right. Change the value of Enable 32-Bit
Applications under (General) to True.
Note that the word “Enable” in the setting doesn’t mean “allow” as in
“allow either 32- or 64-bit applications.” It actually means “force”
as in “force the worker process to run in 32-bit mode so that 32-bit
applications are supported.” This means that the app pool worker
process will always be launched as a 32-bit process when this setting
has a value of True. Setting it to False will launch a 64-bit app
pool worker process.
Note that when an app pool worker process is started, it shows up in
the Image Name column on the Processes tab in Task Manager as
w3wp.exe. When the Enable 32-Bit Applications setting has a value of
True, it will be listed as w3wp.exe *32.
IIS Express 7.5 (as used by Visual Studio 2010 if you install it) is 32 bit only:
http://learn.iis.net/page.aspx/1265/iis-75-express-readme/
To quote:
Both 32-bit and 64-bit systems are supported, however only a 32-bit build of IIS 7.5 Express exists.
So I can't imagine that your problems would be related to the usual 32bit / 64bit pool mode issues that can arise if all of your DLL's are 32bit.
However if you're trying to load a 64 bit COM DLL then this will fail; 64 binaries can't be loaded into a 32 bit process and vice versa.
Another gotcha is forgetting to tick the Use IIS Express checkbox when choosing which web server to debug with:
If you don't tick that checkbox then you'll run your site in a child application in the DefaultWebSite on the version of IIS7 that ships with Windows.
The DefaultWebSite runs in the DefaultAppPool, which in 64 bit versions of Windows runs as a 64 bit process. So you need to change the DefaultAppPool to run as 32 bit if you want to use this instead and consume 32 bit binaries.
You need to do this using IIS7's MMC snap-in or by running the appcmd.exe tool from the command line.
Set your compile target to x86 instead of AnyCPU or x64. Your dll will always run in 32-bit without you needing to mess with the IIS server settings.
the issue is that my source is hosted on the host machine (in this case a mac book pro) and visual studio wants to be able to monitor the web.config for changes so it is throwing the error:
An error occurred loading a configuration file: Failed to start monitoring changes to: \path\to\web.config
I have tried to add the HKLM\Software\Asp.Net\FCNMode=1 but it doesn't seem to work. Also, I don't see moving the source to the VHD as a viable option due to version control issues.
Windows 7 64-bit
Visual Studio 2008
VMWare Fusion 3.01
Thanks.
You have the right idea, but need to edit the correct key for Windows 7.
Open up RegEdit
Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\ASP.NET
Add a REG_DWORD registry entry called FCNMode and set its value to 1
Re-boot and you should be good to go. The "Wow6432Node" allows you to set this for Windows 7 64-bit Visual Studio.
It looks like you can now change FCNMode in your web.config. They probably added it in .NET 4.5, could not find any of documentation but this, but it seems to work.
<system.web>
<httpRuntime fcnMode="Disabled"/>
I'm no filesystem/virtualization expert but I'm guessing that the account that the dev server process is running under does not have permissions to access the configuration file (web.config). The accounts within your VM won't recognized by OS X either so you won't be able to change the permissions to get it to work in this way.
What I would suggest would be to add the IIS component (via Control Panel->Programs->Turn Windows Components on or off) if you haven't already. Then add an application to IIS with the virtual directory within the VHD of your VM. Now to debug, first publish your application to the newly created IIS application (something like http://localhost/MyNewIISApplication) and attach the VS debugger to the IIS worker process w3wp.exe (i.e. Debug->Attach to Process...).
I don't see a problem having the working copy of your code on a VM if the code repository is somewhere else.
I am having an issue related to executing a .Net dll from a classic asp application on a 64 Bit Windows Server 2008 server running IIS7. The situation is as follows:
I have written a .Net C# assembly to perform some encryption tasks. This assembly has been made available to the classic ASP environment via inheriting from ServicedComponent, ensuring the assemblyinfo file has the ComVisible(true) attribute, and it has been installed using the "regsvcs" command line.
When testing on my own desktop (XP running IIS6) everything worked fine. When moving to IIS 7, Windows Server 2008 I get the infamous "ASP 0177 Server.CreateObject failed".
I have tried the following to no avail:
Ensuring the ASP and Script Extension features were installed on the server, as this is not the default for IIS7. This allowed me to execute simple ASP commands, but not server.createobject for the .net assembly.
Enabled 32 Bit application support for the app pool supporting the classic asp site
Used NetworkService as the identity for the app pool supporting the classic asp site
Tried registering dll using regsvr32, which failed
I am able to create other objects such as "scripting.filesystemobject"
Moving dll's to the wow64 directory and then using regsvcs to register them.
And yes when I have been executing the regsvcs commands they have been from a command line launched with "RunAs" Administrator. The regsvcs commands have registred successfully
from both the 64 and 32 bit versions. However, when used from the classic asp application, it fails.
This question is closely related to this one. However, I think this question was more related to using tools on the server as opposed to a programatic problem similiar to mine.
Anyone have any more ideas to try?
After a lot of help here and some more research, we finally came across the answer. To solve our issue we did the following:
No longer inherit from ServiceComponent (This is ok, since we are not actually leveraging any specific COM+ features)
Utilized the following commands to install the component, which must be done in order:
gacutil /i "C:\Inetpub\wwwroot\ASPTest*name of dll*"
regasm /tlb "C:\Inetpub\wwwroot\ASPTest*name of dll*"
This process eliminated the original errors and also had the added benefit of being able to replace the dll while IIS is running.
Try this
Component Services -> Computers -> My Computer -> COM+ Applications
Open a COM+ Application object.
Open Components.
Right-click on a class and select Properties.
Under "Advanced" there is a check box for "Allow IIS intrinsic properties".
It works for me
Create a vbs test file and try to create your COM object there. If you can't (i.e. you get the same error) then your component is not registered correctly.
If you can - then it was installed correctly and the problem is with the lack of permissions for the account your application is executed under in IIS.
I have written a small ASP.NET application. It runs fine when running it with the small IIS installation that comes with Visual Studio 2005, but not when trying with IIS. I created the virtual directory in IIS where the application is located (done it though both IIS and VS 2005), but it does not work. In the beginning I thought it might be caused by the web.config file, but after a few tests, I think that the problem lies with IIS (not certain about it).
Some of the errors that I get are
Unable to start debugging on the web server. The underlying connection was closed: An unexpected error ocurred on a receiver. Click help for more information
Can anybody give me a suggestion of what to try next?
Have you run aspnet_regiis?
Here's an overview site for different IIS versions setup and should help if there are other questions/issues
Try reinstalling aspnet_regiis.exe.
If you are using .net frameworkype 4.0 and using 64 bit system,
Go to Run, Type cmd and Command Prompt will be up, then type
%windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_regiis.exe -i
If you are using 34 bit system,
Go to Run Type cmd and then type
%windir%\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe -i
The site won't load at all or you can't debug remotely?
Some thoughts:
Make sure you've got debugging enabled in your web.config, if you're trying to debug. Otherwise, build in 'Release' mode.
Make sure your project is set as an application, and is running as the correct version of .NET
More description of your setup and the error message would be useful.
Make sure that the customErrors is set to off in the web.config. That should show the actual exception.
Make sure that your virtual directory in IIS is set to the correct version of the .NET framework.
Look at the properties in the virtual directory and see that the correct default documents are the ones that you are using in your dev project.
Also look at the url headers for the website in IIS.
On some of our servers we have both versions of the .NET framework. In IIS I typically have to set what version the virtual directory should be using. This can cause problems running it on the server.
First make sure you have installed and configured IIS server. To check whether IIS server is installed: Run->inetmgr press enter.
To know how to install and configure IIS server check the following Link:
http://chalaki.com/install-iis6-windows-xp-professional-sp3-setup-run-csharp-cgi/425/
To develop Website using Visual developer with IIS instead of "default ASP.NET Development Server", In the new website window under "Location" click on "Browse" to see the different Server options including IIS Server. User can select the server as IIS server instead of "File System", then the "Location" option will be "HTTP" instead of "File System".
In Visual developer 2008 under Properties->Start Option->Server->"Use local IIS server" option is not shown, Even though IIS server was installed and configured successfully. the only options shown are "use default server" and " Use custom server with base URL".
So in Visual developer 2008 to run on IIS server(If IIS server is installed), Need do the following:
New Website -> Under Locations Click on "Browse" -> Click on "Local IIS" and then select the "IIS Virtual Directory"(IIS vitual Directory which is directory created by the user while configuring IIS server) -> Open
While Running/debugging, the server which you selected while creating the website, the same server will used to open the website, that is while creating the website if you selected "IIS Server" then the website will be opened though IIS server.
One more thing is, while installing Visual developer 2008 and IIS server, If you installed IIS server after installing Visual studio then you need to do the following before creating new website:
Run ->cmd press enter (then enter the following Command)-> C:\WINDOWS\Microsoft.NET\Framework\Version# aspnet_regiis -i press Enter then you get message after 3 seconds "ASP.net was installed successfully".
(*Version# will be v2.0.50727 in most cases)
