Hi All, I have an Office 2007/2003 environment. I have deployed Office 2007 compatibility pack for Office 2003 workstations. I've been trying to get a Filter to block installation on Office 2007 workstations, here is what I have... Root\CIMv2 SELECT * FROM Win32_Product WHERE (Caption LIKE "Microsoft Office%2003%") It still will install on 2007 workstations Thanks! Thomas
