Launchpad Won't Export Crystal Reports

Launchpad Won't Export Crystal Reports

If Launchpad suddenly stops exporting reports (even though reports are still running fine), the issue may be that the TEMP directory on the server is full. Newer versions of Launchpad should automatically clean up the directory, though this can sometimes stop working.

The default TEMP directory is defined by the %TEMP% variable for a user, it defaults to C:\Users\[username]\AppData\Local\Temp. For a system account on the server like IIS, it would be: C:\Windows\Temp.

There is a limit on the number of TEMP files because the way the names are auto-generated. The file names are in the format of "tmp0000.tmp" through "tmpFFFF.tmp"—the 4-digit hex number imposes a limit of 64k files. 

Check the C:\Windows\Temp directory on the server running Launchpad for 64k temp files - older files can be deleted to get things running again.
