a DLL is missing problem with MKVToolnix on Windows 7

[loninappleton]

I've used Toolnix for many years. But on one PC (not my second one on a homenet ethernet) a DLL error has appeared.
It is not solved with first deleting the old with RevoUninstaller and then getting the new download at Moritz's site.
Information from Moritz on this is from 2012 or something.

The error is on dxgi.dll. The info on that said it's related to direct x.

Can my DirectX be updated? Is it on the motherboard setup disk? I have no ability to run command line
software patches or installs since I don't know how.

From seeing google entries, this dxgi.dll and some other dll errors have cropped up with users going back
years. Is there a solution aside from reinstalling my Win7 and losing current jobs and data? Does the
Win7 Repair disk fix any of this?

Last thing: SFC /SCANNOW does report 'one or more errors' in it's message. It says that scannow
cannot fix it.

Worst case is I can transfer my work files (for subtitles and such) to a backup HD. But that is a
process where I can miss things.

Just install directx.

Thanks. I'll report any progress.

I got the auto installer package from Microsoft, ran that and did a fresh restart. Unfortunately the error is still
there. Other help sites say getting dll's from the net is taking chances. Is it possible to get the dll from my backup HD
and put that in the proper directory? Any other suggests appreciated.

Try the platform update:

Yes that was the first thing I did-- it was just at the top of a Google search. It ran fine. But after it
failed, I didn't know if it was just a program extension needing the root DirectX.

Yes I also saw that note before making my inquiry here. It's from 5 years ago and there have been lots of Toolnix
updates since then.

But in that note it refers to Windows Media Framework which I know nothing about. That's not Net Framework or it would
be called Net Framework. Toolnix works on my backup PC, a mirror system of most programs I use. That has loaded fine.

I'm going to see if I can tease out the DLL and copy it to my mirror system for any errors.
If crosstalk is an issue, here is a screen shot I made yesterday from the Everything directory search tool-- which looks at everything.

You can see where the dll is installed a number of places. I don't know what various installers do, so it is all news to me.

I ran the dll diagnostic program in System32 and no errors were reported that I could see. I don't know what the
digital 'signing' is for so I don't know if that is related to the failure to load error.

I will look at the non official builds link above.

However I'm calling the problem solved with this solution:

I checked my mirror PC where there were fewer updates and rolled back to old version called v60gui....whatevs.
The program loads fine now on the problem PC. My OS is old. I haven't seen any features changes in MKVToolnix
so this brings the functioning program back.

Thanks to all who've answered on it and I'll report back if, after a restart etc., the problem comes back.

The non official MKVtoolnix thread was interesting. The short answer is without all the stress of subscripts on v. 67, the user is safe getting up to version 66. I didn't know about the incompatibility issue until seeing the thread so I won't bother with any upgrade notifications.
