I just upgraded from version 4.53 to the latest and for some reason it's not running. We normally ran it by running kix32.exe in AD logon script under the profile tab.

I also tried different commands like:
kix32.exe kixtart.kix
kix kixtart.kix

Nothing has changed except the version. Could there be something different about the newest version that affects how it is supposed to be run?
