AML 1.5.1 doesn't launch

[ducki3x]

AML 1.5.0 works fine, but AML 1.5.1 does nothing when launched (either normal or as admin); app never opens, a log file isn't even generated. Have tried placing the folder as a peer of AML 1.5.0, put it on desktop, tried fresh downloads, no joy. Any recommendations for next troubleshooting steps?

Are you sure, that you extract all files from the archive?
Other that that, you could take a look at the windows event viewer, after starting AML. Its not unlikely, that windows will log some error there. Look in the category Windows Logs\Application.

Just deleted the folder and unzipped the package again, here's what I see - let me know if I'm missing something:

Regarding the event viewer, I opened it up and tried launching 1.5.1 several times. Each time, the system did the same thing: my mouse cursor switched to a spinner for a couple of moments, then went back to being a pointer. Each time, I refreshed the application list in Event Viewer, but nothing new appeared:

I also tried going back to an older package and forward to a new one. v1.4.1 loaded just fine for me, v1.6.0 alpha would not. For whatever reason, v1.5.0 is the last version that will run on my machine. I know of at least one other person having the same issue, the OP here:

Do you have some Antivir stuff running, which could be blocking AML?
You may also want to check if Windows is blocking something https://support.microsoft.com/en-us/windows/protection-history-f1e5fd95-09b4-46d1-b8c7-1059a1e09708

Fully disabled Norton, no change. Checked out the Windows Security protection history page, nothing blocked. I also tried the upgrade path on the app, extracting over a copy of my (working) 1.5.0 install, no luck there either.
