Mac Update to 3.5

HI

On my mac (27" imac os 10.15.6 catalina) I just selected the download & install update when I started musescore. The pop up came automatically.

I then quit the program, and when I started musescore (2nd time) he update was not installed - and I was prompted again to download.

So, I did the download again just in case.

3rd time starting musescore - I am still getting prompted to download the update.

I have searched my desktop, my downloads folder, and the musescore folder in the documents folder.

No sign of where this update downloaded to.

Any ideas?

Help!

Thank you

Adam
