I am also getting the same error after upgrading from Office Pro 2003, just when I try to run Outlook 2007, th rest of the package runs fine.
I've try to run repair from the CD too.
"Failed to register a VB script DLL. Re-install or Run RegSvr32 exe Vbscript.dll to self register. An error occurred while creating a form.
Ran RegSvr32.exe Vbscript.dll from the run command.
"The module "vbscript.dll" was loaded but the call to DllRegisterServer failed with error code 0x80004005"
