IIS on my development computer stopped working. I just installed the latest update to windows 10 (1803) and now when I try to start the "Windows Process Activation Service" I get an "Windows could not start the Windows Process Activation Service on Local computer. Error 2: The System cannot find the file specified" error. Things I have already tried:
Reinstalled IIS and Windows Process Activation Service, several times
I verified that I do have a "C:\inetpub\temp\appPools" folder
Not sure what to do next.
I have had this problem twice after a windows update. The issue seems to be, that windows adds an incorrect parameter to the WAS service startup parameters. I fixed the issue using the following steps:
Start regedit (just type it into start)
Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WAS\Parameters
Delete the NanoSetup variable. This variable is preventing WAS from starting
Start the WAS service using task manager or by typing "net start WAS" in Command Prompt
Start the W3SVC service the same way
You can now start your website in IIS again
I had the same problem and nothing in here was the solution for me for a long time. So i rolled back windows also. Today i found the solution working for me - Navigate to:
C:\Users\All Users\Application Data\Microsoft\Crypto\RSA\MachineKeys\
find these 3 Key-files...
d6d986f09a1ee04e24c949879fdb506c_*
76944fb33636aeddb9590521c2e8815a_*
6de9cb26d2b98c01ec4e9e8b34824aa2_*
... then in Security-Settings:
first, you have to set your User as OWNER
close Properties Dialog - and open again
Then in ACL set "full controll" for SYSTEM
After that: WPA can be started...
Hope this helps; see also thread here: https://social.technet.microsoft.com/Forums/en-US/315841e1-b8b2-4084-8224-580ef3d13420/upgrade-to-windows-10-1709-iis-fails?forum=win10itprosetup
I had this same problem after installing the Windows 10 1909 update and the nanosetup variable was NOT in the registry. I ended up doing a variation of Sascha's fix.
I took ownership and gave administrators full control of the MachineKeys folder in C:\ProgramData\Microsoft\Crypto\RSA. Then I removed the 3 files in Machinekeys that begin with:
d6d986f09a1ee04e24c949879fdb506c_*
76944fb33636aeddb9590521c2e8815a_*
6de9cb26d2b98c01ec4e9e8b34824aa2_*
The Windows Process Activation Service (WAS) started as expected.
It just has a simple solution, you don't need to reinstall Windows or removing updates, It worked for me so sharing it with all of you,
if you already using IIS and have site's configurations and files in C:\windows\system32\inetsrv\config and C:\inetpub\wwwroot, Back up all files from the folder C:\windows\system32\inetsrv\config and C:\inetpub\wwwroot, if you are installing ISS for the first time then you don't need to have a back up.
On Taskbar right-click on Start button select 'Run', type appwiz.cpl hit Enter.Click on 'Turn Windows features on or off'.
Uncheck 'Internet Information Services' and 'Windows Process Activation Service' click OK button.
After restarting Windows, Delete 'inetpub' folder on C: drive.
Open 'Turn Windows features on or off window' again.
Check 'Internet Information Services' and 'Windows Process Activation Service' click OK button.
After restarting Windows open folder C:\windows\system32\inetsrv\config.
Right click on the file named 'applicationHost' Select Open with Notepad.
In Notepad, Copy all the content of the file.
Select New in File Menu and Paste all the content in the new file.
Save this file in C:\windows\system32\inetsrv\config with the name 'applicationHost.config.tmp', Don't forget choosing 'All Files' in the 'Save as type' box.
Otherwise, file will be saved as applicationHost.config.tmp.txt which will not work.
Type 'Services.msc' in Run, Find 'Windows Process Activation Service' in Services window.
Watch running the service successfully without any errors after clicking on start.
I finally had to give up and rollback the windows build. To do this follow these steps:
Go to settings (Windows+I)
Click on "Update & Security"
On the left click on "Recovery"
Then under "Go back to the previous version of Windows 10" click "Get
started"
It rolled back to "1709" and now works fine.
If you find yourself installing an application on a drive other than C: and that application relies on IIS, the path for inetpub temporary files may be missing. Even if they are present on C:, this may just confuse you into thinking they are present and thus not the issue.
Create the following empty directory structure, replacing G: with the drive letter that your application is installed to, other than C:.
G:\inetpub\temp\apppools
Then, start WAS, from an administrator command prompt:
net start WAS
If this has to do with IIS, restart for good measure, from the same prompt:
IISRESET /restart
This solved my problem when installing a third party application.
I received the same error after update, but on Windows Server 2022 Standard 21h2.
Tried all steps without success.
In my case WU deleted all params in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WAS\Parameters
so i took it from old ControlSet002:

I have a line of code that I can run locally as part of a service that works perfectly fine.
sReportPath = objCrystalUtils.ExportReportToPDF("Report Name", iReportInfoID)
This code is run as a part of a service, and when I unit test it by feeding it data, it ultimately builds the report and prints it.
When I run the exact same piece of code inside an .ashx from an ajax call. The reports are generated (I can see the pdf files being created on disk) but the printing is not happening.
oRpt.PrintToPrinter(objReport.DefaultAutoPrint, True, 0, 0)
In both scenarios the same code is used to print the report. (objReport.DefaultAutoPrint = 0 in both cases)
My only thought is that the location of the code that is calling this method is in a different spot relative to the location of the bills themselves.
The printer that I'm trying to print to is a network printer intalled on my machine, and I'm running Windows 7 IIS 6.1
Any thoughts?
Edit:
Here is a thought... if I'm running one as a unit test locally and im running the other through a web app that is running via IIS, is there a difference in user id and user access to the default printer?
Edit:
So I added my local ASP, IUSR and SYSTEM users to the printer security and allowed them to print... no dice. So I checked the EVERYONE user and it is set to access and NO users are denied... so I think that kinda kills that line of reasoning.
Edit:
I changed the name of this post since I no longer think that the issue is ajax related since If I try to do the same process in code bebehind from a post back instead of running it from an ajax call i still get the same problem.
Patrick, for me it is a known issue of crystal reports, printing a certain report from a running application via IIS.
I got the same issue before, and upon our search for that issue, we got the following;
Report to be generated, exported, and then to be downloaded to client machine,
so user can print it locally (say, report will be exported as PDf file,
user can use print option of PDF reader).
It's not Crystal Reports or other third party app's problem. It's usually the IIS_IUSER's permission problem because it has no access to any network printers. A possible solution is in Process.Start doesn't work in IIS
I am developing a Qt application, and I've been asking some friends of mine to test it. One of them told me that he can't run the application. Here is the error he gets:
When he presses yes, then he gets a "mingwm10.dll was not found" message. Of course there is mingwm10.dll in the working directory and then it says "application stopped working" error. When he presses no, it opens PeaZip.
I've tested the application successfully on Windows XP, Windows 7 and Windows Vista, so I really have no idea what's going on. (However, my friend is using Windows Vista, if that's helpful)
So, do you have any idea what it means?
From PeaZip's user manual (PDF):
If a single archive file is dragged to the browser PeaZip will show a
disambiguation popup to ask if adding the object to the archive or
rather opening it.
So if I have to guess he is either not putting the executable and other files into a clean directory, but into an archive, or directly trying to run the application from the archive. Have you by any chance wrapped everything into a single zip file which you gave him?
Make sure everything gets put into a clean directory and try running the exe from there.
I have an NSIS installer that installs my Qt application. At the end of the install process, the installer gives the user the option to launch the application immediately.
My application uses QLocalSocket/QLocalServer to talk to other local instances of the application. (They talk to each other basically just to ensure that there's only one instance of the app running at a time.) However, on Vista, if one of the instances was started up by the installer, then other instances cannot talk to that instance unless they were also started by the installer (or uninstaller, interestingly).
The NSIS installer launches the app with the Exec command. The client tries to connect to the server through QLocalSocket::connectToServer, which fails with the error "QLocalSocket::connectToServer: Unknown error 5".
Can anyone explain this? What's the best way to work around it?
If 5 is a windows error code, it would mean access denied. Is there a way for you to change the security on this server (You would need to access the native pipe handle)?
The finish page run option has more issues than just this, the new process gets the wrong HKCU and user profile etc.
I would recommend just disabling the run checkbox on the finish page. (This issue goes all the way back to win2000 when RunAs was added)
If you really really want this run checkbox, you can use the UAC plugin, it will allow you to start a child process as the "correct" user.
Finally figured this out. The installer was running as admin (the install script said "RequestExecutionLevel admin"), and apparently it launched my app with those elevated permissions, which meant that other instances of my app running with user-level permissions couldn't connect to it. QLocalSocket/Server uses named pipes on windows, so I figure this is a windows security feature. I'm planning to work around this by using the UAC NSIS plugin, which I believe lets you run a process with user-level permissions.
I need any tool or IDE environment to debug and test the vb scripts code. Please suggest any free ones. My vb scripts are standalone (vbs extenstion).
VBSEdit
Not free, but has an unlimited trial period with a nag screen.
Sadly not free....How to debug Windows Script Host, VBScript, and JScript files
I think you'll have a hard time finding a free tool that supports real VBS debugging. But I've used this "poor man's technique" in the past. Create a variable at the beginning of your script
blnDebug=False
Then throughout your script add lines to echo what the script is doing or the value of different variables:
if blnDebug Then wscript.echo "Now starting script strFoo=" & strFoo
When you set blnDebug=True then all your debug messages will be written to the console (I always use CScript when running this). By adding these debug messages as you write your script, you can have debugging available simply by changing the bldDebug value.
Certainly commercial editors like PrimalScript include a debugger. SAPIEN also has a standalone debugger, http://www.primalscope.com/, that while not free is a relatively inexpensive option. You can download an eval copy to try it out.
There is a really old tool called Script Debugger for Windows NT 4.0 and Later. It is designed for VBScripts running in web pages but you can attach it to a vbs script easy enough.
You can download it from here:
http://www.microsoft.com/downloads/details.aspx?FamilyID=2f465be0-94fd-4569-b3c4-dffdf19ccd99&displaylang=en
The name says NT 4.0 I know but I am currently running it on Windows 7 x64 and hod no problems opening the debugger.
Simply install the above tool then run your script from the commandline like:
wscript.exe myscript.vbs //d //x
Once the debugger opens you can step through code and even open a command window where you can check variable values by typeing ? Varname.
