File cannot be exported, 'failed to save as ..... the file writing plug-in failed'

Hi guys
I am trying to save a SAT file to be exported as an Autocad file

But I am getting this error.
“Failed to save as C: , The file writing plug-in failed”

I am using Rhino 2020 on Windows.
Can anyone please help as I am working on a deadline, but cannot seem to get it to export at all. I have tried multiple YouTube videos and forums, but no luck at all.

Any help will be greatly appreciated!


Is this with one particular file, or with any file you try to save as .sat?

Can you run the SystemInfo command and copy/paste the results here?

Where do I get a copy of Rhino 2020? :wink:
