Affinity start and install fully broken (Photo, Designer, Publisher)

[DAVKLE]

Trying to start either programs result in one of these two scenarios. All versions are 2.5.7.

1. Stuck in Loadscreen forever. Clicking on the box results in a Windows error.
2. Stuck in Loadscreen titled "Initialising..." until a popup appears to check your firewall settings. Same happening with firewall fully deactivated. With and without IPv6 enabled (normally I run IPv4).

Trying to reinstall the software (all 3) result in the installer erroring out with the following message:

Cannot open app package
Reason:
Error in parsing the app package.

Windows 11. Latest updates.

Nothing recently installed, deinstalled or changed on the system. It just stopped working today.

How do we fix this now?

Welcome to the forum!

Maybe this older topic helps you:

But why do you want install version 2.5.7? Latest version is 2.6.2.
