Running EASE seems to be causing AutoCAD (from Autodesk) to want to run its installation routine. How do I correct this?
If running EASE always causes Autodesk AutoCAD (or a related product) to run its installation routine, this is most likely an indication that the installation of AutoCAD was somehow corrupted and needs to be repaired. To correct this problem please go to the Windows Control Panel, choose Programs and Features, then click on Autodesk AutoCAD (or the related product) to perform a repair or reinstall.
