Fabrication 2026 Error

[VirtualPilot]

Every time I start a fresh run of the program I am getting this error, once you click OK it works fine, until you start the program again...

Same.

For not ever adding features or fixing things...they sure seem skilled at breaking things every release.

Thanks Darren, wasn't sure if it was something I did and installed it incorrectly...

[Andy Robins]

Is anyone else experiencing this issue?

I don't have this issue in 2026, but have had this previously. This post from Autodesk fixed my problem by updating ODIS.

Is this happening with CADmep? If yes, did you install the recent AutoCAD 2026.0.1 update?
I can reproduce when using the latest AutoCAD update in fact.

I'm guessing the new install included the latest version, but yes, 0.1 update...

Odd, that was posted almost a year ago...

I'm getting it with 2026 only
2022 no issue.

windows 11 2026
windows 10 2026 no warning

I would also like to throw my hat in the ring.
This error appears whenever launching Fabrication CADmep, but functions normally after clicking OK.
I also noticed Fabrication CADmep does not appear in the License Manager window, as it does for 2025 and previous.
Windows 11, AutoCAD 2026.0.01

Same error

Make sure you update all the licensing through Autodesk Access, not sure if it was a Windows 11 Update or Adesk's Update, but have my money on a adesk update fixed it on my end.

I just updated using the one they just posted on Jun 4, still have the same issue...
