MediaMonkey forum

Decided to move forward from latest MM2024 version to the new MM2027 Beta Debug. Downloaded and installed to my usual location with the usual portable option, with the "run after install" option set. Installed OK but crashed with an error message I hadn't seen before - "app.utils.system is not a function", mentioning "macpatches", log automatically submitted. Rebooted computer and started up MM2027 first thing, same error. Rebooted and started with DbugView running. Will raise a helpdesk ticket.

This is caused by old and not compatible script macPatches, it is not distributed already few years. Just delete it from your Scripts folder.
I will try to solve it better as in related issue here: https://www.ventismedia.com/mantis/view.php?id=20078
