Good news on our test system here since we last tested in Oct 2021 when it was failing.
As of 24 Jan 2022, AmiBroker and its OLE capabilities are now working.
Our environment:
Mac mini (M1, 2020, 8GB RAM)
macOS Monetery 12.1
Parallels Desktop v17.11 (51537)
Windows 11 for ARM v22538.1010
Amibroker v6.30.5 and v6.40.3
As to the matter of which update in which environment actually fixed the issue - we don't know. Bringing all of the above up-to-date has solved things here in the environment documented above.
Cheers,
Richard.
