Reinstalling an Operating System

If you reinstall the operating system on the computer where your Autodesk license resides, the license can fail. As a result, you would be unable to use your product, and you would have to reactivate your license. The following procedure prevents a license failure when reinstalling the operating system. See Activation.

Note: The following procedure is for the Windows operating system. If you are running Autodesk products on Mac OS X or Linux platforms, see your product supplement to Installation Help for more information.

To prevent a license error when reinstalling an operating system

Note: If using Norton™ Ghost™ or another image utility, do not include the Master Boot Record.

1. Locate one of the following folders and make a backup copy:
   • (Windows XP) C:\Documents And Settings\All Users\Application Data\FLEXnet
   • (Windows 7, 8, Server 2008 R2, or 2012 R2) C:\ProgramData\FLEXnet
2. Reinstall the operating system and reinstall the Autodesk product.
3. Paste the license folder to the same location from which you originally copied the folder in step 1.

   You can now run your Autodesk product.
