Urgent: Having issues installing AutoCAD 2010... help!

I'm running into a wall while trying to install AutoCAD 2010. This screenshot pretty much sums up the frustration:

The AutoCAD installer itself won't even let me select it for installation.🤷

Does anyone have any insight into why this is happening? I'd appreciate some help here—this is critical for my current workload.

Thanks in advance.

Run CCleaner to scrub your registry—it’s pretty obvious you’ve got leftover junk from a previous version hanging around. If that doesn't do the trick, just fire up the Registry Editor, search for "AutoCAD," and manually wipe out every single key you find.

I tried it again, and still nothing works.🤷

Is there any other way?😕
