Here is the error:
System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.Web.Administration, Version=7.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.
The machine that gets this error has Microsoft.Web.Administration version 7.9.0.0 installed, but not version 7.0.0.0. The reference to this assembly from EWL is to version 7.0.0.0 but has Specific Version = False.
Could this be an IIS Express issue? I know that EWL has never been tested with IIS Express.
The machine is running Windows XP.
