Just updated to version 4.2.1 from previous version on Win 10 system and all is fine. Installed on Win 7 laptop (my programming computer) and the VCM Editor will not open. Repaired several times and no change. Uninstalled and reinstalled several times and no change. Computer shutdown after each change. The new Beta version functions fine. How do I get back to previous stable version? Note: On both systems, the new update was not found thru Help/About. It stated no update found in the pop-up box. I got the new version thru the website by downloading the latest suite. The VCM Editor has a pop-up box that states "VCM Editor has stopped working - A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available." Windows states program in not compatible. Win 7 Ultimate 64 Bit Service Pack 1 - fully updated and licensed version.
