The ASP.NET process identity does not have read permissions to the global assembly cache
Posted by Mikhail Esteves under: Tips; Windows .
The simplest way out of this is to ensure your virtual directory has explicit Read & Execute permissions for the ASPNET account. Failing which, uninstall IIS & Visual Studio, and re-install everything from scratch!
You may also want to ensure the assembly folder in your Windows directory gives the ASPNET account read/execute permissions too.
