Unity 5.6 - APIUpdater encountered some issues and was not able to finish.

No idea what’s causing this but everytime I open my project it asks me to upgrade the API and then fails. I can’t find anything obvious in the log.

APIUpdater encountered some issues and was not able to finish.

Same here… on both Mac and PC. Really need to get the project to 5.6 because of a bug in 5.5 preventing me from building to Android.

Exactly the same error?

I fixed this myself. I ran the updater, then searched the editor log for “upgradable” and manually fixed the issues. There was only 2. Not sure why it didn’t fix them automatically.

@derkoi : Thank you for your answer. For now I tried not running the API Updated at all (and everything is still working just fine). It also will show the deprecated lines. In my case, deprecated API’s are used from the Vuforia .DLL which I can’t change . So I guess I’ll have to wait for an update.

Another thread referenced this reply, and I wanted to mention here as well that the steps listed here worked for me. Thanks!

Thank you for this answer, this solved my issue as well.
