Install Scripts fail on Win Server 2008

[MRKiscaden]

I have an InstallScript Custom Action (InitInstallDir) that is launched immediately after the CostFinalize action. Right now, It simply writes to the MSI log and returns. This Custom Action works perfectly in Windows XP and Windows Vista. However with Windows Server 2008 I get the following error:

[CODE]MSI (c) (50:D0) [16:24:39:788]: Doing action: InitInstallDir

What is going on? I have no clue where the "PROPERTY CHANGE: Deleting ALLUSERS property." is coming from. That is not from my Custom Actions.

Do a search for Deleting ALLUSERS. Lot's of good hits including:

Looking at the logs on other platforms where the scripts are not failing, they also have the "Deleting ALLUSERS" line. I am more concerned about the error "Script function f9 failure. Unknown Exception." since it is preventing my installer from functioning at all. Any insights for this one?

One more detail: I have the same Problem on Windows Vista x64.

Perhaps my install script engine is no-good?
