Well, disabling UAC might be a good hint as it helps to exclude lots of possible problems. However I left UAC turned on on all my Vista machines mainly to find issues with UAC by myself in order to be able to gain some experience (quite masochistic approach , huh) :-) Up to now I did not have such deployment problems even while UAC is turned on as long as I was using the (default) SYSTEM user within the WPKG client configuration. SYSTEM user does not seem to be affected by UAC issues. But probably the problem of the thread initiator is completely different. I suggest to analyze the WPKG log files (including debug output) as well as monitoring processes during WPKG execution: - Is the installer process actually run? - Any installer log file written? - Which exit code is returned when the installer process exits? br, Rainer |
