Hi!
Assuming your application runs under a "Network Service" host, please try switching your application temporarily to a host process with "Local System" security context. To do that select the application in UWS Explorer and click "Move to another host process" | "Move to new host...". If application starts working properly under Local System account, then the issue is probably access rights. To check whether that's the case, move application back to a "Network Service" host and add read access rights to "v2.0.50727" folder under C:\WINDOWS\Microsoft.NET\Framework.
If that works, please let us know - we may be able to make our web server grant proper access rights to those folders during our product installation.
