Where is the IIS Express install directory?
Locate the registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\IISExpress\<Your version>
and parameter "InstallPath
".
My directory is located here:
C:\Program Files\IIS Express
The user Data files are present here:
C:\Users\[username]\Documents\IISExpress
If that's the error. Then you might have got the error 404.13 (Forbidden) on your browser.
You can try to edit the web.config file and add this:
<system.webServer>
<modules runAllManagedModulesForAllRequests="true"/>
</system.webServer>
This would allow the server to read the files and process them. This is a server settings error. And I think this might help you out.
Update
As suggested by jamiebarrow, you can get to that directory directly using the following path in your Windows File Explorer,
%userprofile%\documents\IISExpress
