Environment
LonMaker 3.2
Vista 5.1.0, 5.1.1, 5.1.2
Windows Vista
Cause
When the Vista Toolpack 5.1.0 was developed, LonMaker did not support Windows Vista limiting the ability to test for compatibility and all problems. As a result this problem is only experienced when launching Zbuilder from LonMaker.
Resolution
Upgrade the TAC Toolpack to version 5.1.3 or higher. If Vista Server is being used as well then ensure that the Toolpack and Vista Server versions are still the same revision.
