Problem

When running ProjectWise Web Server, users are presented with the following error message; "ProjectWise Web Server evaluation license has expired. Please notify System Administrator"

Solution

If there is HKEY_Current User \SOFTWARE\Bentley\Licensing\1.1\Applications listed in the registry delete everything under Licensing.

You can set up logging in the licensetool.exe.  If it is still not obtaining a license, search under Hkey_Users for Bentley\Licensing and delete anything that is found under licensing.  

Then do tools, send logs now.  It should now obtain a valid license. Refresh your browser and log back in. 

On the server, open IIS and change the default application pool (DefaultAppPool) Identity to NetworkService. Once that is done, perform an IISReset.
