Yesterday the program, running under Windows 7, would not start properly. A notice popped up saying 'sldworks has stopped running' A second window popped up saying Windows would search for a solution, but nothing further happend automatically. I closed the computer , rebooted - still the same. Uninstalled the program, rebooted, reinstalled it - still the same. Called up command window and set up CHKDSK C:/F and ran this check. No problems reported. Tried uninstalling, rebooting and reinstalling again - still the same result. Can anyone please suggest what is wrong or what I should do now?
