We recently had a customer contact us and they mentioned that they had issues with activating their Autodesk software. They mentioned that something had gone wrong and the activation could not be completed.

I checked their PC using remote tools like Teamviewer and I could also could not activate the software.

I suggested that we uninstall the Autodesk software and thereafter also delete the activation and licensing information.

To uninstall you can either install software using the Windows Add/Remove Programs tool in the Windows control panel or you can use the Autodesk Uninstall tool. This tool usually get installed as part of the Autodesk Suite software installation or you can download the Autodesk Uninstall Tool here : http://a360.co/2qGIjdp

In the example screenshot below you can see that the tool picks up all the Autodesk software on your PC and you have the opportunity to uninstall using one click. In the example I selected the Revit 2018 software to be uninstalled.

Now that all the Autodesk software has been uninstalled you can delete the licenses.

First look for the FlexNet directory in C:\ProgramData\ path and delete the content.

Then delete any files inside the following folders:

C:\Program Files\Autodesk\

C:\ProgramData\Autodesk\

C:\Program Files (x86)\Autodesk\

C:\Users\All Users\Autodesk\

C:\Users\YOUR USERID\AppData\Roaming\Autodesk\

C:\Users\YOUR USERID\AppData\Local\Autodesk\

Thereafter I would strongly suggest to use registry cleaning software like the free CCleaner utility to remove any registry entries that have been orphaned in the above process.You can download the CCleaner utility here : https://www.piriform.com/ccleaner/download

Reboot your PC and begin the Autodesk installation from scratch.
