Remove association for .mui files

I was trying to open C:\Windows\System32\en-US\shell32.dll.mui with Resource Hacker & it kept saying it couldn't find the file (even though I dragged it into the resource window). In playing around with it, I accidentally made Resource Hacker the default for opening .mui files (I don't know what was the default, if any, before).

I used File Types Manager to go to .mui file types. Double clicked it to bring up the Edit screen. Removed Resource Hacker (from the command line) & clicked the 3 horizontal dots:

to bring up the next screen.
& clicked Detach File Type. However, it didn't give me the option to say "ok".
Now, all the .mui files have the Resource Hacker icon & double clicking opens the .mui file. How can I put it back the way it was before I screwed up?

Thanks in advance.

Hi, check you have nothing for that extension in these locations:








You could suggest Brink adds mui to this tutorial:

From that you could check and compare the content of e.g. the txt reg file which I used as a basis for the above in case I missed something.

Thank you so much!! The first image was set for Resource Hacker & as soon as I deleted the value for mui, the icons change back to white & they don't have an associated app to open, so that did it.

I went through the other images & also removed the "OpenWith" option...although I suppose I could have left it.

I will inform @Brink about it tomorrow.
