Recently we are running into problem with our advertisement. In the windows\system32\ccm\log\execmgr.log file the package is been reinstalled once a day. In the past we never had this problem. According to the log the program did install successfully but it starts again. It does not happen with all the systems. Any one had similar experience. I already spent long hours looking into this and still no answers...

here is part of the log.
