During the normal course of action, infoRouter creates temporary folders for various reasons.
A series of tests are performed at application startup to make sure that the required resources are available to infoRouter. During this check, it was determined that temporary folder creation attempt returned an error.
Depending on your temp drive location, you must make sure that infoRouter has been granted appropriate permissions.
On IIS 5 and IIS 5.1, the ASPNET account temp folder is profile based and is usually stored under "C:\documents and settings" folders.
On IIS 6 (Windows 2003) the Network Service account temporary folder is located under the WINDOWS\tmp folder.
Make sure the path specified in the error exists and the ASPNET or the NETWORK SERVICE account has full control permissions to this path.
On Windows 2003 make sure that the NETWORK SERVICE has full control to the C:\Windows\tmp directory.
