Attempted Complete Uninstall/Reinstall but deleted registry too soon

[Anonymous]

The latest windows 10 update has caused autocad architecture to start crashing. I wanted to do a complete uninstall and reinstall so I searched for how to do that and found I needed to uninstall it in add/remove programs and also remove it from the registry. While the main program was uninstalling I deleted some of the registry files I read to delete. Autocad (the main program) completed the uninstall but then I went to uninstall "Autodesk Material Library 2016", "Autodesk material library base resolution image library 2016" and "Autodesk material library low resolution image library 2016" and it said, "there is a problem with this windows installer package. A DLL required for this install to complete could not be run. Contact your support personnel or package vendor".

How do I complete the uninstall??

You may need to contact support.  Never edit the registry while an uninstaller is running.  The only time to clean up the registry is after all the program components have been uninstalled.  Start by using a registry cleaner before doing things by hand.  There are also lots of other folders to consider removing that are left behind after uninstalls.

For others following this thread, consider rolling back the Creator Update before uninstalling AutoCAD. It's also wise to create restore points after installing software so that you can roll back to a working restore point.

Hello @Anonymous,

It's recommended to only try to conduct the steps here for a Clean Uninstall of the program to remove user & program files use MSfixitTool to complete the uninstall of registry keys.

Let us know how it goes.

And clicked on the Microsoft fix it link, downloaded it for each portion of cad that was still leftover and then followed the remaining instructions on a clean install. I was able to reinstall 2018 and it's working much better now.
