Changing location of file storage

Hi,

I'm trying to figure out how to relocate the drive where SEUM stores the tmp.hdmp files.  Right now they go to c:\users\SEUM=User-1\AppData\Local\Microsoft\Windows\WER\ReportQueue

Since we keep out c:\ drive very small I want to change the default location to the E:\ drive.  Where do I go to look for this setting?

Thanks

Marc
