Same here… Nevertheless, I took my backup disk and installed OpticsPro versions 8, 9 and 10 on my Apple Silicon MacBook Air and checked with the Go64 app. All OP versions reported as 64 bit apps. I then simply launched the apps in demo mode (too lazy to enter license codes) and looked at what I got:
- OP 8 registered okay but closed immediately. OP8 would not run
- OP 9 registered okay, opened and seemed to work as expected
- OP10 registered okay, opened and seemed to work as expected
Note: All OPs had to be launched with ctrl-click (first time only) to force gatekeeper to accept the apps. All apps installed from installers I had downloaded from my account with DxO in Summer 2020.
The cause of the issue is therefore probably not 32/64 bit, but maybe an exceeded install limit? We lack info on how many different computers @Billm has already installed OP10 before.
DxO support might be able to check this…
