Client has an Access database on the D: drive of a particular server.  
MSAccess is installed in the Program Files directory of the C: drive on the
same server.  Client needs to compact/repair the database on the D: drive due
to sizing issues.  There is enough room on the D: drive to handle the copy of
the database that is created when performing the Compact/Repair.  ISSUE: For
whatever reason, the Compact/Repair process is writing some files to the C:
drive (MS Access Installation) during the Compact/Repair process and the C:
drive doesn't have enough capacity to handle these temporary files.

Why are temp files being written to C: when the Original database and the
compact copy are on D:?  How can I stop Access from writing the temp files to
C:?
