After installing ACT 5.6 ,log processing kept failing with following Event 0 ACTUpload: ACM database version is incompatible. Logs cannot be processed. I followed this to install and configure ACT http://www.techforcast.com/2012/04/act-56-setup-step-by-step.html On the Machine following event appeared everytime it tried to process the logs. Since i had choose to create DB on separate SQL 2008 R2 SP1 Server and used System Account for Log Processing Service , i needed to add the following permission to system Account of the ACT machine on that DB. After this is done , move all the files from Failed folder to the root of ACT File Share and restart ACT log Processing Service. . Additional tip: In order to push the Data collection package silently using SCCM, i used the following command msiexec /i dcp001.msi /qn Hope this helps.
