Total failure of plugin

[effree]

Problem to Solve

I was able to download and install the latest version. But as soon as i click on My Styles, or Table Styles (since I've turned on the error popups), it says:

"An exception occurred while calling function "GetStyleGalleryItemCount". The exception message is:

Unable to cast COM object to type 'Microsoft.Office.Interop.OneNote.ApplicationClass' to interface type 'Microsoft.Office.Interop.OneNote.IApplicationCOM'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{452AC71A-B655-4967-A208-A4CC39DD7949}; failed due to the following error: Error loading type library/DLL. (Exception from HRESULT: 0x80029C4A (TYPE_E_CANTLOADLIBRARY))."

After clicking okay, I can now see the menu next time i click on the dropdown, but nothing functions. Checking the logs, i have more of the same style errors.

To Reproduce

Steps to reproduce the behavior:

1. Go to 'Any Dropdown Menu on the Ribbon'
2. Click on 'Anything'
3. Nothing happens

Expected Behavior

To be able to open the menu's without error. To be able to click on menu options and see other parts of the addon. I can't even click Settings or About OneMore, because nothing happens.

Environment (if applicable)

• OneNote Version: O365, 64bit?]
• OneMore Version: Latest

Additional Context

I have reviewed and seen some similar errors, but none were exactly the same. Either way I've done the following testing:

1. Uninstalled OneMore multiple times and reinstalled
2. Tried using the repair for OneMore
3. Updated all of the latest Windows 10 updates, including all .NET Framework updates that were available to be through Windows Update.
4. Uninstalled All Office Applications and my Standalone install of OneNote
5. Reinstalled OneNote only and installed OneMore
6. Uninstalled OneNote again, and reinstalled Office Suite
7. I restarted between each step above.
8. Installed OneMore again

Still getting the same error.

THE FINE PRINT This is a hobby project that I started for myself. I'm happy to take requests and will promise to
consider each one carefully but offer no guarantees that I will ultimately agree to their
usefulness or have time to implement any of them. If OneNote offers a "close enough" work-around
then I will probably reject the request - you've been warned!

Rename this file %APPDATA%\OneMore\Themes\Default.xml to Default-hide.xml and restart OneNote
If that works, please send me that file, attach it here or share online.

If it doesn't work, trying renaming %APPDATA%\OneMore\Settings.xml to Settings-hide.xml and restart OneNote
If that works, please send me that file.

I don't see either file in that directory.

I tried installing a newer .NET Framework so i went with 4.8.1. Restarted, Repaired Office Again, Removed and Reinstalled OneMore and still have the same above issues. It appears to not create the files that you expected it to create. I think it could be an issue with mscorelib. I checked my c:\Windows\Assembly folder, and i have legacy versions of that file/dll but i don't think i have ones that are being harnessed. No amount of google is helping me find a way to replace the file if it is missing. I'm also not sure if it should be in the program files/river directory with all the other .dll files.

Additional Research:
I can't seem to find {452AC71A-B655-4967-A208-A4CC39DD7949} in the registry in the location I expected to see it. I'm wondering if the wrong CLSID if being grabbed, due to old versions being installed at some point or something.

Also, like I mentioned before, there is no mention of mscorlib.dll on my system anywhere, so it could just be that this is missing, but after looking all over the internet, I can't find anyone with a similar issue.

1. Is there a place I should be finding this dll on my system, so I can check the specific location?
2. Do you have a list of all registry key entries you try to create when installing, so I can hunt them down and see if they were created properly?
3. Do you know where I should specifically be finding this CLSID from my error logs on the registry? If it is not there, what should it have under it and I can manually attempt to create this.

[stevencohn]

It should be here HKEY_CLASSES_ROOT\Interface\{452AC71A-B655-4967-A208-A4CC39DD7949}
and possibly here HKEY_CLASSES_ROOT\WOW6432Node\Interface\{452AC71A-B655-4967-A208-A4CC39DD7949}
same for HKEY_LOCAL_MACHINE\Software\Classes... and a couple of other spots.

I believe it's the CLSID of the OneNote IApplication interface, which tells me that your OneNote and/or Office installation needs to be repaired (I know you mentioned you tried that though!).

OneMore is built using .NET Framework 4.8. You've installed 4.8.1 which should be backwards compatible with OneMore. The mscorlib.dll should be in a few spots including something like C:\Windows\Microsoft.NET\Framework\v4.0.30319\mscorlib.dll and C:\Windows\Microsoft.NET\Framework\v4.0.30319\NativeImages\mscorlib.dll as well as in the GAC

Thanks for looking into everything with me. I'm kind of at a point of exhausting all my knowledge. I ran the repair again, offline and online, both for Office and OneNote, and still cannot get it to work.
I ran ProcMon filtering by the PID of the plugin. It called msocorlib.ni.dll from C:\Windows\assembly\NativeImages_v4.0.30319_64\mscorlib\316b66ba76e2cd70541b5fe8161637c9 and didn't seem to cause any noticeable flags in there. I scrolled through everything in there with no major issues.
I checked the Windows Event Manager and saw the same message that you output to the log file, but nothing else.
I also tried to run regsvr32 on the dll in 3 separate locations, all of which didn't work.
At this point I think it might be related to something that my company is doing on their permissions or registry or something like that.

[effree]

I found a fix for my issue. In case anyone else has this problem in the future.

1. I ran ProcMon from SysInternals.
2. I filtered to only view the PID of the running OneNote.
3. Then started capturing and tried clicking on the OneMore Addin in the ribbon. Then it started registering information in ProcMon.
4. I then stopped capturing and worked through the very first part of the dllhost.exe information. I noticed I was getting PATH NOT FOUND for the OneNote application location.
5. I went into the RegEdit at the location it was checking which was HKCR\TypeLib\{0EA692EE-BB50-4E3C-AEF0-356D91732725}\1.1\0\win64
6. This was pointing to a folder where there was no OneNote.exe. It was looking at C:\Program Files\Microsoft Office\Office16\ONENOTE.EXE\3 instead of C:\Program Files\Microsoft Office\root\Office16\ONENOTE.EXE\3. (missing the root folder)
7. I made this change to the registry entry and the add-in began working immediately.

[stevencohn]

That's really interesting. I wonder if running the Office installer in repair mode would have caught that.
I could look into adding a check to the installer to verifiy OneNote registry settings and warn when they look strange.
Thanks for the info.

[effree]

No problem, and also just so you know, I did run the repair a few times and it never picked that up or fixed it. Not sure why, but I am also on a domain network. The install we use for 365 products is managed by a part of the IT team, and it could be related to how that installer is being used. The installer is for Microsoft 365 Apps for enterprise - en-us and OneNote was installed separately. Both repairs failed to work multiple times as well as full uninstall and reinstall. The only fix was to manually edit that location.

Glad to have it fixed, thanks for everything, can't wait to finally use this thing.

[stevencohn]

Added pre-install verification of OneNote configuration. If any suspect settings are detected, a warning dialog is shown prior to installation.
