Hello! Ive recently got a new PC and downloaded AP packs that I had on my old one. Ive managed to download the Class 158/159 (Cummins) pack, however, every other pack I download I get as far as the installing process at choosing the destination folder, after clicking allow for the bit where it says “would you like to allow this app from an unknown publisher to make changes to your device?” I get an error message which says “Error 2503. Called RunScript when not marked in progress.” After clearing that error message I immediately get another one which says “Error 2502. Called InstallFinalize when no install in progress.” This is happening every time, and on every location I have chose to put it in. If anyone could help me out I would greatly appreciate it. Im on an Acer PC (cant remember what model) and it is running Windows 11.
You might get better help at the AP customer service / website. It's possible that DTG or other players have an idea, of course.
