Troubleshooting

– If you are unable to activate your product, or the activation crashes:

• Try uninstalling the July 2014 Microsoft security update
• Try downgrading your Internet Explorer (IE) from version 11 to version 10 by following the instructions detailed here
• If all else fails, call Autodesk – they can authorize your software for you; you will need to give them proof of purchase, your serial number and request code.

– If you have crashing problems using the File->Open or File->Save dialogs inside of AutoCAD please read this blog entry on the File->Open or File->Save Crash in AutoCAD
