This is *not* just related to IE7. I slipstreamed only windows updates using nlite and found the same problem while running office for a new user because it needs to run the msi installer the first time any office application launches (see my posting). It should be a bug in the nlite slipstreaming process which does not change the registry key permissions on that key. I just checked another system that was installed by hand and the default permissions on that registry key should be: Administrators - Full Control System - Full Control Everyone - Read When changing this permissions on HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer make sure you set them to propagate down by selecting the check box that reads: "Replace permission entries on all child objects ..." I can't find the values for those permissions at that registry key location. May you be more precise about where they 're located please? thanks
