Sudden Errors during Installshield build

[garyb@se.rr.com]

I have all of the sudden started getting the following error message; (excerpt from VBP log.)

Resolving strings...
Language English (United States) built
Building CAB files...
ISDEV : error -5044: Cannot delete directory c:\temp\DIR837.tmp
ISDEV : fatal error -5087: Stop at first error
CPC32\CPC32 - 2 error(s), 0 warning(s)

I am on version 6.7 and using InstallShield Pro 12 on Vista Ultimate.

I can of course go directly to this location and delete the folder manually using the same login.

This problem does not appear when I create the InstallShield build in the InstallShield IDE.
