Installation of SWV 6.1 SP1 fails on Windows 2000

Hello,

I'm trying to use the Workspace Virtualization Agent in combination with Wise Installation Studio and one of the target platforms is Windows 2000. I had some problems getting this to work. One of them is that SWV 6.1 SP1 does not install on my Windows 2000 SP4 virtual machine. I ran the installer Software_Virtualization_Agent.msi from the command line and had it write a log file. It seems like there is a custom action that fails because a DLL can not be loaded. Here's an excerpt from the log file:

MSI (s) (40:C8) [11:18:02:062]: Executing op: ActionStart(Name=fslxRollbackInstallProductSecurity,,)

MSI (s) (40:A4) [11:18:02:093]: Hello, I'm your 32bit Elevated custom action server.

Any ideas how to fix this?
