Error:" nonvalid software detected"

[stevej]

I  have been running the same 2019 setup for years.  Today this message began appearing: "nonvalid software detected"?  I have 8 perpetual licenses.  Running 6 active 2019 stations without issue.  One station have 2021 which we do not use.  Only two stations have received this message so far.

We have gotten this message on 3 out of 6 of our computers.

I chatted with Autodesk and this is a widespread issue they are trying to resolve.

Did you find the solution? I've just faced the same issue.

[mileyfox568]

yeah i have same question!

Yes. It was an update issue between windows and cad. A windows update changed something and it basically threw off something else in cad. Cad was behind on a patch and/or hotfix.  I wish I could provide more technical info.  It did take a few chat sessions and a call to get what I needed from Autodesk support but ultimately they got me fixedup.  We run c3d 19 and are licensed UpTo 21 so the 19 files, no longer supported, are inaccessible. I think it's a bit of a bad deal but they helped me out as they've done before.
