Hello all.... Just had a fun afternoon tracking down a problem cause. A user started an application and when trying to complete 2 specific functions the applications window exited. Luckily she was the only one piloting the software, so while she was logged on: Started filemon & regmon, set filters to monitor the named process, in this case viztopia.exe, and paused them. Started the application, and progressed to a point just prior to the mouse click that triggered the window close. Started filemon and regmon, completed the mouse click that broke the application, then stopped filemon and regmon from capturing any more info. Looking through regmon, there were no failures. Filemon had a failure referring to MSJTER35.DLL, which was loaded from the common files directory. Knowing this was an OLE DB file, and working on the hunch of the issue being due to versioning, I compared the loaded dll version with the one that was provided by the software supplier: TS server dll version: 3.52.1527.4 Software install version: 3.51.623.0 So, I then copied the older version to the install location of the software, knowing that it searched this directory first for an instance of the dll. I didn't register the dll at this location, and then ran a test. The software loaded the older version and the software worked correctly. Is there anything I should be warned about if I leave this in place as is?
