Error message when trying to install with Mac OS Sequoia 15.5

Hi, I am having trouble installing with Mac OS Sequoia 15.5. It says: ’ You can’t open the application “PortfolioPerformance” because this application is not supported on this Mac. I have installed Java24 and also removed the blocker for applications from outside the AppStore

Does anyone know why this could be the case?

Did you follow the steps as described in the manual?

Sounds like you downloaded the wrong version.

While we are talking about the AppStore, isn’t it the read only version? I recommend Portfolio Performance - Downloads instead.

I guess he was refering to Apples MacOS Security Feature.

Yes, I downloaded it from the website. it says minimum requirement is OS11. I have 15. So I thought it should be fine.

Just choosr the other dmg package. Based on your chip architecture.
