I'm just putting this one out there since its a Google Zero-resulter which means I win a prize?
Cannot start IIS Express 7.5 after reinstall from one account, but I can when logged-in under my other domain account.
What's odd is that the account it fails under is my 'super' account with local admin rights, and is also the account I installed it under.
The error stems from diprestr.dll not loading...

For more information about the error, run iisexpress.exe with the tracing switch enabled (/trace:error).
Any got any ideas? I'll try Process Monitor and see.
So far, IIS Express is proving to be just another thing to learn and go wrong.
Check that the user its failing has a IISExpress\config folder in their home folder. If not then copy it over from the user where IISExpress is working. This is a common fault when the config files/folders are missing.
To clarify John's comment - the directory will be something like C:\users\jmitchell\My Documents\IISExpress\config. I assume John is correct in that if it doesn't exist you would need to create the directory.
Alternatively the directory could already exist and just be corrupted. This is what I believe happened in my case. I had previously installed WebMatrix but ran into all sorts of issues today. After uninstalling IIS Express, Web Platform Installer, WebMatrix, and some SQL Server Management Objects, and then reinstalling WPI & WebMatrix, I came across this post.
I actually got IIS Express to run successfully after deleting the config directory mentioned above, and then re-running C:\Program Files (x86)\IIS Express>iisexpress.exe /trace:error
And I ONLY wasted two hours of my day on this! Thanks Microsoft!
I got this problem after upgrading to Web Platform Installer 5.
The quick fix for me was to also upgrade to Webmatrix 3 (http://www.microsoft.com/web/webmatrix/)
After deleting config folder it was still not working then i followed this article and hit ctrl + F5..so it did run
Only Deleting config folder did not work for me. Also i did this
"Delete the following file <>.vs\config\applicationhost.config, the .vs folder may be hidden"
Also, you might need to change the line
applicationDefaults applicationPool="Clr4IntegratedAppPool"
to
applicationDefaults applicationPool="Clr2IntegratedAppPool"
in the file...
C:\users\jmitchell\My Documents\IISExpress\config\applicationhost.config
if you continue to get the same error (as I did) after following the instructions on the post above. The issue being solved here is that you don't have .NET4 installed, and so are reverting to using .NET2
Thanks
