Reporting breaking after deployment

[Connor]

I am using Telerik Reporting Q2 2015 and it works perfect when running it out of VS in debug mode.  Once I deploy it to an intranet site I start receiving an error

Internal Server Error:
An error has occurred.
Access to the path 'C:\windows\TEMP\Application1\9.1.15.624\LCT\value.dat' is denied.  

Since the server and the dev machine are one in the same (at this point) I was confused why I would get this error.  On the surface this appears to be a permissions issue, but I'm not sure.

Hi Jacob,

The application and the Reporting REST service in particular seem to not have access to write in the local file system. Please test stetting the Application Pool's Identity; or use the second overload of the FileStorage in the service's ReportServiceConfiguration and provide path to a folder with set proper read/write access.

Note that depending on how the application is hosted you may need to switch to other cache storage - REST Service Storage.

I hope this information is helpful.
