I recently had to do a complete wipe/reinstall of Windows from scratch. I've been at it all day today, the only issue I've experienced is with Notion.

I've installed the EU "Windows 10 Pro N" version (64 bit) as it does not come with so much junk, and has a better privacy setup. One of the things it doesn't come with is Windows media player, and that's exactly what MF.DLL is.

So why on earth this reliance on Media Player with Notion? Why is it required? I don't partiticularly want to install it or it's programming libraries, I have J River media center which is a lot better.

Ultimately this is a bug because the library should at the very least have been supplied with the installer, or at the very least we should have been supplied a better error message than "The code execution cannot proceed because MF.dll was not found". A better fix would be to have a build of this software without this reliance of couse, it doen't make any sense to me.

Anyway just gassing off a few thoughts on this before I report this to support, I assume this must have happened before.

If it hasn't happened to you it's because you have Windows Media Centre, if you uninstall it and reboot you'll probably get this issue.

EDIT - DON'T DO THIS.

My workaround was to find my old Windows install and copy the following files:
mf.dll, mfplat.dll, mfcore.dll (search in the Windows folders).
to:
C:\Program Files\Notion 6\

Just in case this helps somebody...

Cheers.

After media player disappearing I was getting mf.dll errors again with 19041.329

My "solution" of copying MF.DLL was probably ill conceived, this is a much better solution, I am assuming you can't find Windows Media Player under "optional features".

If you've manually copied DLL files like I did (not advisable in retrospect), then delete them.

Run Windows Powershell as Admin.

Enter: Get-WindowsCapability -Online | where name -like Media* | Add-WindowsCapability -Online

When it's finished, reboot, then run windows update, and you are probably going to need to reboot after that...

Fixed...
