Hi Vinny,
Sorry to know the problem is still there. But actually the message you saw there was a false alert. You should have already seen some other messages in the matlab command window, which said something like “Extracting code…” and “Copying new code…”. And you will have a tmp folder under lead. I fixed this issue just now. You can delete the tmp folder under lead and click the ‘Apply Hotfix’ menu again. You will still see the error message as before, but no more for next time. Hopefully everything will be fine from now on. Just a hint, the hotfix package is basically updated daily (if there’s new commit on github) before a new release coming. You could try it if you get problems, maybe it’s already fixed on github but not released yet.
Best,
Ningfei
