Do not restore your hard drive or re-image it without first exporting the licenses with the Portable License Utility. Additionally, Inventor needs access to modify the master boot record on the boot drive. This is used to store licensing information. Software that blocks this or periodically restores the Master Boot Record will lead to license failure.
