Decrypt IS file failed about gamefinder

[erri120]

Have you tried running the example? I've set up the CI workflow to publish builds of the example on every commit: https://github.com/erri120/GameFinder/suites/12799382184/artifacts/688986744. The example will log your decryption key.

Just tried.

But they are no key in log.

I have tried on other computer, but same, no key in the log. No mention of EA.
It work with Windows 11 ? I have the latest release.

Thanks for your help !

Thanks for testing! The CI artifact fails due to trimming, and the custom build fails because of some bug I need to fix.

[erri120]

Could you try these two builds:

• trimmed: win-x64.zip
• not trimmed

[EzioTheDeadPoet]

trimmed: log.log
not trimmed: could not download

Enabling trimming disabled COM entirely, which basically makes the feature completely useless. I'll take a look at the cryptography exception, that is likely a bug in my code or EA updated their encryption.

Ok, I hope you will succeed!
Anyway thank you for your work ;)
