Permission denied to create C:\MediaToolkit folder

[jthorpe80]

The package needs to create the folder C:\MediaToolkit upon first use, but our web server does not have write permission granted to the process that creates it and so gets a access denied. Is there a setting that can move this folder location? Why can't it access the files it needs through the \packages\MediaToolkit.1.1.0.1 Nuget folder?
