I realize this may be heretical here but I use a batch file to install a long list of apps and updates after installing XP SP3. In the process I install IE7 and two related updates. The two updates fail to install. Here's the segment of my batch file: rem install IE7 and two related updates start /wait %1\XPUPD\IE7\IE7-WindowsXP-x86-enu.exe /passive /norestart start /wait %1\XPUPD\IE7\IE7-WindowsXP-KB938127-v2-x86-ENU.exe /passive /norestart /log:C:\938127.txt start /wait %1\XPUPD\IE7\IE7-WindowsXP-KB961260-x86-ENU.exe /passive /norestart /log:c:\961260.txt I'll paste the log file below but in a nutshell it says that IE7 isn't installed yet. What can I do to "register" IE7's installation so these updates will install? Thanks!
