I've created an ASP WebForm application that requires "Enable 32-Bit Applications" to be set to true. When I set the site up in IIS I set "Enable 32-Bit Applications" true, but when I look at the Task Manager I'm not seeing the *32 next to the w3wp.exe process that starts up. And when I browse to the site I'm getting "Service Unavailable - HTTP Error 503. The service is unavailable." as the App Pool stops within IIS.
How can I force the w3wp.exe process to start in 32 bit mode?
EDIT- The machine in question is a 64-bit Windows Server 2012 R2 in case that matters
EDIT 2- I found a link to http://www.manasbhardwaj.net/running-32-bit-web-application-iis-8/ Which references issues wile Running Sharepoint 2013, Which is running on the web server. It applied the changes, and now when I run the site I get a configuration Error regarding framework versions.
I find it odd b/c the app pool still is not showing the *32 next to it, but it didn't crash when starting the site.
I'm going to ensure the latest .NET framework is installed now.
EDIT 3- Looks like I need to run a couple of updates on the machine in order to install the latest .NET framework. The .NET framework my site uses is 4.6.1, Is this version Stable enough to run on a Live WebServer running SharePoint 2013?

I am setting up my new workstation (Windows 10 Pro) with my ASP.NET projects with Visual Studio 2017. I have enabled local IIS and the project throws a timeout error while trying to debug the project.
It is not failing 100% of the time though, mostly fails but when it runs it is taking longer than expected to give the startup page. The error thrown is
Unable to start debugging on the web server. The operation has timed out
I did notice that the IIS worker process (w3wp.exe) was only executed in the completed console output. So it looks like the IIS worker process is not always being executed.
Any help would be appreciated!
Thank you!
The project runs successfully on an old workstation (Windows 10 Edu) with Visual Studio 2017. App pool settings has been compared between both and it seems same. IIS reset is tried as well. Visual studio has been repaired and IIS local has been restarted as well (unchecking and enabling followed by restarting the machine). Default app pool is used and its been recycled as well. Nothing worked!
Possibly the Visual Studio project version does not match the ASP.NET configured application pool. Update the ASP.NET version in the application pool and restart it.
Make sure you have the correct version of ASP.NET installed on IIS. A version mismatch between ASP.NET in IIS and the Visual Studio project can cause this issue. May need to set the framework version in web.config. To install ASP.NET on IIS, use the Web Platform Installer (WebPI).
If the issue is not related to IIS configuration, try the following steps:
Restart Visual Studio with administrator privileges and try again.
For example, using the Web to deploy some ASP.NET debugging scenarios that require elevated Visual Studio privileges.
If you are running multiple instances of Visual Studio, reopen your project in one instance of Visual Studio (with administrator privileges) and try again.
If using a HOSTS file with a local address, try using the loopback address instead of the computer's IP address.
If not using a local address, make sure the HOSTS file contains the same project URL as in the project properties, Properties > Web > Server or Properties > Debug, depending on the project type.

I have web app running locally in IIS. App of Net Framework 4.7.2. When I tried "Attach to Process" for w3wp process in Visual studio I am unable to do so. Visual Studio is running under Administrator account. Things I tried:
Restart of IIS and VS in different sequence.
Setting "Enable 32-bit Applications" flag on app pool in IIS to true
Tried to run process monitor to see if there would be errors. Nope, no errors.
Tried manually set type of app in "Attach to" combobox to various types with same results. Types tried: Managed 4.x, with and without Compatibility mode, Managed(Native compilation), Native.
Tried Visual Studio repair - still having issue.
Created brand new web app .Net Framework 4.7.2, deployed it under IIS and tried to attach to the w3wp process and got same issue.
Things I noticed:
When I tried to attached to 64 version of the w3wp the type is "Managed Net 4, x64" and I am getting "Unable connect to the process" message with justification: VS must run as administrator. Funny thing: VS IS running as administrator.
When I turn 32-bit application flag on I am getting type as x86 and plain "Access denied". Even if restart IIS and try to access the app to start new w3wp process. I think it should be: "Managed Net 4, x86", but I am not 100% sure.
At this point I am out of ideas. Any help would greatly appreciated
UPDATE.
I noticed, when I turn on 32bit applications on app pool in IIS I am getting following error in Event Viewer:
"The description for Event ID 0 from source .NET Runtime cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer."
Turned out corrupted Avecto installation was the culprit. Reinstalling offending software resolved the issue. Live and learn. At least I lived.:)
I have a .net mvc web application hosted on an IIS 7.5 web server. There are several dozen other applications on this web server, all in their own application pools. ALL application pools are 64bit and things have been working fine for some time.
Last night after making a few client side changes to the site in question I published and received the error, "Could not load file or assembly 'EntityFramework.DLL or one of it's dependencies. is not a valid Win32 application. See screen below.
I ran into this error several years ago and found that by switching my app pool in IIS to 'enable 32bit applications' fixed it. This time around however, I want to understand why this is happening. There should be no reason I can't run in 64bit mode.
I know the cause could be many things so I will just list some of things I have tried. Perhaps someone has an idea where to start.
In visual studio 2013 update 4 my application is set to build for 'AnyCPU'. I have tried building exclusively for 64bit and got the same error.
I am using EF 6.1.1 with data migrations
My web server is running windows server 2008 64bit w/ iis 7.5
My development machine runs windows 7 64bit and IIS 8 express. My app works fine in this environment
I do have references to other projects that reference EF. If their version is not consistent could this be a problem?
My application targets .net 4.5 and I have that version installed on my server.
The only changes I made to this commit from the last working one were some client side code and one new migration that involved adding a new nullable string/nvarchar property to a table.
I did update to visual studio 2013 update 4 between last commit and this one.
Any ideas? Thanks ahead.
My task is simple: I need to test my ASP.NET web application in a 64-bit environment on my development machine. (At this point I don't even ask about running it through a debugger. All I need is to run it in a 64-bit process.)
So I created a stock C# Web Application in Visual Studio 2010 and adjusted its properties as such:
I then did Ctrl+F5 (or run without debugging) and IE loaded up and hangs up like so:
What am I doing wrong here?
PS. Running it on Windows 7 Ultimate (64-bit).
We had the same problem and when the team jumped to Visual Studio 2012, this registry key was really useful to us :
you can add a registry key to force visual studio to use the 64 bits version of iisexpress.exe ; unfortunately for you, it is a VS2012-only solution.
reg add HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\11.0\WebProjects
/v Use64BitIISExpress /t REG_DWORD /d 1
Then restart Visual Studio and tick [X] Use IIS Express in your settings.
(see also the source).
UPDATE: For reference, in Visual 2013, this option can be found in the interface : Options/Projects and Solutions/Web Projects/Use the 64 bit version of IIS Express for web sites and projects
In IIS make sure the Application Pool, Advance Settings, Enable 32-Bit Applications = false
If this setting is true then the worker process will run as 32bit WOW64 process.

No settings required in project or solution level. I am developing WebApp on VS2010 on 32 bit and 64-bit machines simultaneously. Actually We are working on SVN and our few machines have Win7 32-bit and my few mates have Win7-64bit laptops. But there we haven't faced any such issue while compiling the app on two different machines and Even on the live server, it runs butter smooth. Hardly care about the bit and bytes.
To verify a test run. Publish your code and host in your local IIS or Cassini Webserver and access it over LAN.
Also if possible revert back solution and project settings to its original configuration settings. Generally, We do not need to change target until and unless it is strictly required. As, AFAIK, It compiles the assembly under "Any CPU" as target, which is eligible for all i.e. IA, X64 and X86..
Finally, if you are coming across any error, please do post it here. It will help you and us as well.
First of all how to do you know if your IIS process is running your website as 32-bit or 64-bit as of now?
Open Task manager to check the bitness of w3wp.exe. If your machine is 64-bit then IIS will run 64-bit by default. Your problem seems to be something else. If bitness is the issue then you won't even come this far. Check IIS logs (c:\inetpub\logs{website-ID}{date})... that might give you some pointers. If there is nothing in there, check event viewer. If nothing then check if the virtual directory is actually created in IIS Manager under Default Web Site.
Have you actually tested if IIS (sans ASPX) is functional? http:// localhost ? does that work? if that is working then I would recommend checking if your ASP.NET modules are properly installed within IIS.
Hope this Helps.
For this project I needed to install and run VS 2003 on Windows 7 using IIS 6.0 with Framework 1.1 on my sever because there was old VS2003 C# code on a remote server that needed updating and did not have VS 2003 installed only the DLL, PDB, aspx, and aspx.cs files. After porting the code over and making the needed changes on my local server, I discovered that while I could browse the page, I could not run the page with debugger and got this error: "... Unable to start debugging on the web server. There is no managed code running in the process. In order to attach to a process with the .NET debugger, managed code must be running in the process before attaching." I then started the application without Debugger and selected the w3wp.exe process for CLR in order to attach the process but I noticed that the process session was set to 0 and I still got that error again.
The following is done in IIS6 :
Application created.
DefaultAppPool (.NET framework 1.1 Integrated)(ApplicationPoolIdentity) is used
Browsing the web page works OK.
Authentication has Integrated Windows and ASP.NET Impersonation enabled.
I have runned aspnet_regiis from all the .net version in order
Set debug="true" in the web.config.
Thanks much for your help
Resolution:
Right click the ASP.Net project > Properties
select Configuration Properties > Debugging
Enable the below mentioned entries in 'Debuggers' frame.
ASP.Net Debugging
Unmanaged code debugging.
I had the same problem.
I fixed it.
Delete the virtual directory in IIS
Create the new virtual directory with different name other than the old one and configure the new virtual directory name in your visual studio solution.
