Tried to install on multiple machines but keep getting the following when I click setup.exe:

Error occurred during the execution of Setup.

Arguments:  
Exception: Value was invalid.
Parameter name: sddlForm
StackTrace:    at System.Security.Principal.SecurityIdentifier..ctor(String sddlForm)
   at SourceCode.SetupManager.Program.ensureUserPrivileges()
   at SourceCode.SetupManager.Program.applicationReady(Stringy]& sArgs)
   at SourceCode.SetupManager.Program.Main(Stringa] sArgs)

My Configuration:

Windows Server 2008

SharePoint Server 2007

Anyone have any ideas?

Thanks
