QUESTION: When I start PR-Tracker I get the following error message: Error 430: Class does not support Automation or does not support expected interface PR-Tracker Web Client 5.10.0073 Prtrackerwc:Main Prtr:OpenProject ProjectDb.CreateDb ProjectDB.PopulateStatusLookupTable prwebcli ANSWER: This error can occur if you have an invalid MDAC installation on your computer. PR-Tracker requires that MDAC 2.5 or higher be installed on a computer to run. PR-Tracker installs MDAC 2.5 (with no service pack). The are many ways that an MDAC installation can be invalid and Microsoft provides and MDAC checker which you can download and run to troubleshoot your MDAC installation.
