Reports run fine in HTML format but attempting to run the report in any type of Excel format fails. Restarting the Cognos 8 services would resolve the issue temporarily.
No cm folder exists in the \temp directory. Seemed that there was script on the Cognos 8 server that was run nightly as a clean up tool and it removes any temp directories that are empty. This script would remove the c8/temp/cm directory that is created only at startup. The subdirectories of the /temp directory had been deleted. (cm, cam, cogconfig, cqe and rsvp)
Windows 2003, Unix
Manually create a folder called ‘cm’ under the Cognos 8 temp directory.
Restart Cognos 8 (which will create all needed directories)
Navigate to the c8/temp directory and make sure you have the following folders cm, cam, cogconfig, cqe and rsvp. If any one of them missing then create new folder .
