I cannot install Scaler 2 on my Mac Sonoma

I just purchases Scaler 2. I donwloaded the pkg file but i cannot open it. A message is shown that it says : The operation couldn’t be completed. (com.apple.installer.pagecontroller error -1.)

I tried a couple of things like download again the file or restart the laptop but nothing happened. Does anybody have an answer for that?

Hi @jimi_hayes Where did you purchase from?
