Same thing here with Custom & Vintage and Metal Foundry on Windows 10. I also tried rebooting and redownloading of the updates – no change. However, I noticed that the updater process is still running in the task manager consuming 12-15% of CPU on my machine. But even after more than half an hour nothing happened.
Progressive Foundry and Music City updates worked like a charm though (same machine, same setup, same steps).
