Geekbench 6 doesn't install correctly under Windows on Arm (on Ampere)

I tried installing Geekbench 6.0.2 on Windows on Arm on an Ampere Altra Max system (see—the M96-28 variety—and the installer seems like it completes successfully, but the actual Geekbench 6 binary/executable is nowhere to be found.

A shortcut is placed in the Start (Windows?) menu, and when clicked it says the original file is missing. If I look in the Program Files directory for Geekbench 6, I see some .plar (or something like that, can't remember off hand) files, but no exe.

I also downloaded the latest version of Geekbench 5, and it installed and ran through all the tests without issue. I will link to the test result on a follow-up comment in this discussion.

    Here's the Geekbench 5 result for this system:

    With the 6.1.0 preview release, I was able to get a result:

    However, (a) it seemed to only be hitting like 30 or so of the 96 cores on my system, so the multicore score is wildly inaccurate, and (b) the script launches (after dismissing a security warning), the tests run... but then the script window disappears immediately after the last multicore test runs.

    The only way I was able to find my result was browsing the Geekbench 6 'recent results' page; but I can't claim the result because I was not given a claim key :(

    For a., I'm not sure what's going on with the Geekbench 6 multi-core score. The workloads that typically scale well on workstation processors (such as Clang and Ray Tracer) aren't scaling as well as I'd expect. It could be there are threading issues unique to workstation processors on Windows on ARM.

    For b., if you run Geekbench from the command prompt instead of Explorer you should be able to retrieve your claim key. In the meantime I've added the result to your account.
