I've come across what appears to be a very minor bug while integrating IE7. I can't say it is caused by nlite, however, the problem does not occur if I install IE7 into an existing XP install, only when integrating. And again, it's minor. It would only affect User accounts, not Admin users. I have integrated the Final IE7, downloaded directly from MS, no other changes, into a plain XP SP2, with no other integrations, changes, or anything. What is happening, is the rights to the registry key, HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer are being changed. On my pre-IE7 image, that key has the following permissions: Administrators - Full Control SYSTEM - Full Control Everyone - Read (Query Value, Enumerate Subkeys, Notify, Read Control) on my post IE7 integration, that key has the following permissions: Administrators - Read (Query Value, Enumerate Subkeys, Notify, Read Control) SYSTEM - Read (Query Value, Enumerate Subkeys, Notify, Read Control) Since there are no other rights, this triggers a couple of MSI errors (2503 followed by 2502, on EVERY MSI). Again, since most normal user accounts do not have the rights to install software via MSI's anyway, and most home users are Admin users, it's not a big issue. I only came across it because we deploy software to restricted users. Can anyone verify this?
