OneMore OneMore Not Active (ARM64)

What happened
Environment Win11 24H2 ARM64, Office 365 ARM64 Microsoft® OneNote® for Microsoft 365 MSO (Version 2510 Build 16.0.19328.20000) 64-bit OneMore 6.8.0/6.7.7/6.7.6/6.7.4

Learned from the issues, tried as many solutions as possible, but the result is still frustrating.

Thanks for running the iq and setregistry scripts. With setregistry did you run it with the -reset parameter?

And I assume you've click the box in the COM Add-Ins dialog above? Wait a few second and, if it is going to load, it should immediately without even restarting OneNote.

Otherwise, the only thing that has worked for other people is to reinstall or repair-install OneNote or Office. I do not know what's preventing it from loading. The --install-checkonenote action should check everything that is needed. There must be some configuration that it's missing.

Sorry I could not be more helpful. I do not have an ARM64 machine to test this on.

Oct 04 '25 11:10 stevencohn

yes, setregistry with the -reset.

sometimes after click the box in the COM Add-Ins dialog, onemore goes to actived immediately without even restarting OneNote as it shows. but it does work, not display in the ribbon. after restarting OneNote, onemore goes to inactive again...

maybe i'll try something else after win11 25H or o365 update...

PS: installed onemore is arm64, but OneMoreTray.exe is x86...

Oct 04 '25 11:10 Test-Acount

~~Try this .\setregistry.ps1 x64 -reset~~

Sorry, nevermind, this won't help.

Oct 04 '25 11:10 stevencohn

I'll take a look at the x86 OneMoreTray image. That't not right. But it shouldn't prevent the add-in from loading

Oct 04 '25 11:10 stevencohn

I have the exact same issue too on my brand new Surface Pro 11 (Windows ARM). I have Windows 11 home 24H2 and installed the ARM version for OneMore on my Office ARM build OneNote app.

Oct 08 '25 07:10 anonymous199-ai

I don't know from which version of Windows 11, but it seems that Microsoft no longer particularly emphasizes the difference between x64 and arm64. I wonder if this is related?

It happens for me too.On ARM64 Surface.

Is that correct? The Onenote is X64,but displayed as ARM64(x64 capable)in Task Manager. I also find some document about arm64 and arm64ec [ARM64EC](https://learn.microsoft.com/en-us/windows/arm/arm64ec)

It says the arm64ec program cannot load pure arm64 binary(DLL?) but only ARM64EC binary and X64 Binary. The New ARM64X mix up ARM64 and X64 by using a forwarder.Might be useful?

So if you can build it on ARM64EC,It may increase capability on Office.Weird office architecture...

But I found .NET does not support ARM64EC? https://learn.microsoft.com/en-us/dotnet/standard/native-interop/abi-support So Do someone who successfully running on ARM64 machine can share your experience?

@Test-Acount @nekoteai @tsuliwaensis , others...

Can you please try this test release: https://github.com/stevencohn/OneMore/releases/tag/6.8.1-prerelease? If you are running OneNote x64 on your Arm64 machine, download the x64 msi. Thanks

Oct 27 '25 16:10 stevencohn

@stevencohn Great!

OneMore_6.8.1_Setupx64 works for me, it seems all right.

OneMore_6.8.1_SetupARM64 can not install.

Oct 28 '25 10:10 anonymous199-ai

An interesting tidbit, not sure if it's useful at all - I had the same issue (not loading). I used 6.8.1 x64 installer (it's a VM running on macOS). OneMore is not visible in the ribbon BUT I can add commands to Quick Access Toolbar and they work fine.

Tried to de-select and re-select in Ribbon Customization, doesn't help

Oct 28 '25 23:10 KrzysztofNawara

@KrzysztofNawara Hm. Is this showing that the Customize Ribbon dialog shows it there but it's not visible?!

Oct 28 '25 23:10 stevencohn

Actually, try closing OneNote, deleting (or renaming) your %appdata%\OneMore\Settings.xml file, and restarting OneNote please

Oct 28 '25 23:10 stevencohn

@stevencohn Great!

OneMore_6.8.1_Setupx64 works for me, it seems all right.

OneMore_6.8.1_SetupARM64 can not install.

Today, I installed a .NET Framework Preview Update (KB5067931) and restarted my computer.

Since I wanted the ARM64 version of OneMore, I decided to give it a try.

I uninstalled the OneMore_6.8.1_Setupx64 version and installed OneMore_6.8.0_SetupARM64 instead, but it still didn’t load.

So I tried reinstalling the previous OneMore_6.8.1_Setupx64 version.

However, that didn’t work either—it also failed to load. (setregistry.ps1 -reset not work)

Oct 29 '25 01:10 Test-Acount

@KrzysztofNawara Hm. Is this showing that the Customize Ribbon dialog shows it there but it's not visible?!

Precisely. But as long as I can add specific commands to Quick Access I can live with it. But it could be an explanation as to why some users believe it's not actually active, when it is.

By the way, it used to work just fine. I think it may have been broken by one of the Office updates. I noticed it after upgrading OneMore, but then I went back to 5.9.0 (which was fully functional) and it still didn't fix it.

Actually, try closing OneNote, deleting (or renaming) your %appdata%\OneMore\Settings.xml file, and restarting OneNote please

Doesn't seem to have helped. But as you can see, Navigator still works just fine :)

Interesting! OneMoreCalendar.exe works for me.

Oct 31 '25 10:10 Test-Acount

@KrzysztofNawara The OneMore tab on the ribbon, next to the Help tab... is that a tab that you added? Otherwise, that is what you're looking for. That was added in v6.7.1.

You can switch back to the group on the Home tab from the Settings.

It's documented here https://onemoreaddin.com/the-basics/Basics.htm

Oct 31 '25 10:10 stevencohn

@stevencohn I'm a moron. Thanks! I was still looking for it under Home

Oct 31 '25 10:10 KrzysztofNawara

@KrzysztofNawara No worries!

@Test-Acount seems like you have a different problem? Note that OneMoreCalendar.exe is a standalone app, separate from the OneMore add-in. That's why it should always work.

Oct 31 '25 10:10 stevencohn

OneMore_6.8.1_Setupx64 and OneMore_6.8.1_SetupARM64 not work for me

Oct 31 '25 11:10 Test-Acount

@stevencohn Tested with OneMore_6.8.1_Setupx64. When OneNote is run as an administrator, Onemore loads correctly. However, when OneNote is run normally, Onemore fails to load.

Nov 04 '25 11:11 Test-Acount

That's interesting. I think. I don't know what it means or why that would be true. But it's interesting. Thanks.
