Any idea what's wrong when upgraded my iMac to MacOS?

[epeepleasant]

I've been using Helicon Focus since 2016. Helicon Focus has been frequently opening in Demo mode since I upgraded my iMac to MacOS "Big Sur" last March. I didn't realize this until I saved a stack image as a tiff file, only to discover that it was a low-resolution version with an embedded watermark. Then I have to look for my license key again, register, and re-run the stack. This is quite aggravating. Do you have any idea what is wrong?

No, we don't know why it's happening and it's not a common issue, but make sure you have the latest version of Helicon Focus. The new versions have automatic mitigation for this issue, so it sounds like you're using an old one.
