I just had to do this yesterday. Check out the MS KB link and modify the registry or files as needed according to the IE version matrix[^]. In my case the installer checked for IE 5 for NT. With Procmon running, I only updated whatever registry keys where checked by the installer and then restored them once the installer completed the checks. It also worked to fix the check for an older version of a Windows Service Pack, an old Adobe Acrobat Reader and an old Java Runtime Environment. Jeremy
