Issue:<\/strong><\/p>\n\n\n\n

After installing a newer version of AutoCAD (e.g., AutoCAD 2023), AutoCAD 2016 crashes upon launch. It may open successfully once after a system restart, but subsequent attempts result in an “Invalid License” pop-up and crash.<\/p>\n\n\n\n

Cause:<\/h2>\n\n\n\n

This behavior typically indicates a conflict or corruption in license components shared between different versions of AutoCAD. Installing a newer version can sometimes overwrite or modify files essential for older versions’ licensing, leading to validation failures. The deepuninstaller<\/code> tool aims to resolve these underlying licensing issues.<\/p>\n\n\n\n
