Cannot Load Addins

[Anonymous]

Please view the attached photo to see error messages. This happens on startup, and I am not sure if it is affecting performance in CAD. The errors seem to be associated with CAM.

Hi,

Sorry for the trouble.

This is a known issue associated with the new UI preview. Do you have that turned ON? Check Preferences > Preview and look for the item "UI Preview". Un-check that box, if it's checked, and restart Fusion.

If it's not that, I will escalate this to product support.

Thanks,

Thanks for your response. That box was NOT checked, and the problem
persists.

Hi @Anonymous

Thanks for posting! This error message is usually related to an installation or update error rather than the add-ins it references. Please perform a clean uninstall and reinstall Fusion 360 - this should eliminate the error.

In my experience, this warning is purely cosmetic and does not seem to effect the normal operation of Fusion 360. Please let me know if you see any behavioral problems - I am happy to continue troubleshooting.

Thank you for your reply and solution.

I did have to delete a file called "webdeploy" first because something else was missing.

The program now starts up clean and fast.

Thanks again,

Happy Modeling...
