Hi,
I followed every advice, but still cannot apply my license key.
I opened the photoscan-pro_1_3_1.dmg package and movde all 4 files to the applications folder. In my security settings, I selected "allow apps downloaded from: Anywhere"
But still, I get the message "can't write license file"
What else could be wrong?

Edit: I solved the problem with the terminal and this command: PhotoScanPro.app/Contents/MacOS/PhotoScanPro --activate ...
