Solution

This problem may occur when an a particular user does not have the required permissions to write to the Temporary ASP.NET Files directory of the host machine.

For more information on the Temporary ASP.NET Files directory see http://msdn.microsoft.com/en-us/library/ms366723.aspx

To give the particular user the required permissions, open command prompt and redirect to the directory that holds the Temporary ASP.Net Files directory; which should subsequently be by default:

cd C:\Windows\Microsoft.NET\Framework64\v4.0.x\

And execute the following command, making sure to replace |SPECIFIC_USER| with the desired Service Account.

aspnet_regiis -ga "|SPECIFIC_USER|"
