I recently converted a project from IS2010 to IS2011 and notice that the administrator's TEMP environment variable changes once in Deferred Execution. In Immediate Execution, it is located in C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp\1, where I expect it to be. However, once in Deferred Execution, it changes to C:\Windows\Temp.
Any idea why it changes?
I opened up the IS2010 version of the project and confirmed that it remains pointed to C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp\1 throughout the install. The custom action VBScript code is contained in an external file, so I am using the same CA code in both versions of the install.
I'd rather not have to begin to account for this switch in all my projects that I intend to upgrade to IS2011, so some information about this would be much appreciated.
Are you using the InstallShield built-in SQL scripts support in your installation? If so, apply the hotfix posted in this thread, and see if it fixes your issue.
