Re: Windows 11
 

Im not the only one with this issue it seems

https://answers.microsoft.com/en-us/...a-da6eb765fc5b

When i double click an MP4 it asks me what i want to do with it, now i can choose each time to play it but i cannot associate that file type with ANY player including VLC.

Re: Windows 11
 

Did you try the fix on there ?

The name implies it may only fix images, but worth a shot.

You can probably edit the registry as well, but I dont know how much its changed since W7/W8.

pot player even

ok my method works perfectly

Re: Windows 11
 

you may need to browse to the exe of potplayer but as I say following these steps associates an mp4 with potplayer

Re: Windows 11
 

As i stated the option is greyed out, everytime i choose to play an MP4 i have to manually choose what player i cannot set as default app as the option is greyed out.

It doesnt give the option to always use the app

Re: Windows 11
 

As u can see i have no option.

Re: Windows 11
 

That list has a scroll bar. What’s at the bottom of it?

Re: Windows 11
 

is that from default app list or the right click menu ? what version of 11 are you running?

also have you tried reinstalling the app and selecting ALL in the file association option ?

---------- Post added at 17:35 ---------- Previous post was at 17:31 ----------

in the default add on list select file type and mp4 then select pot player from there and repeat for other video types this should work. For some reason Pot Player does not show in the App list ( mind you it might if I restart but it does show in file type list)

Re: Windows 11
 

Just an option to scroll for more apps to open with thats it unfortunately.

Running 11 Pro and yes uninstalled and reinstalled both Pot Player and VLC and chose for MP4 to play default and still the same.

I have tried to type MP4 and choose Pot Player but nothing appears its just greyed out.

Re: Windows 11
 

it is quite strange how your version of pro is different from mine.

Ok try right clicking on the mp4 and selecting properties you should see an opens with attribute with change next to it. Select change and then click pot player that should do it for mp4 permanently. If not go to church cuz God only knows hahaha

Re: Windows 11
 

I can right click and select open with but i cannot choose it permanently

Maybe if i do a fresh install instead of an upgrade these issues may clear up so when i have a few hours to burn i will do so..

Re: Windows 11
 

Have you tried a different .mp4 file?

(in case the one you are trying is corrupt)

Re: Windows 11
 

That wont make any difference, it simply works off the actual extension.
You could create a empty text file with an .mp4 extension and it should still work (ie try and open it with your video player of choice).

Re: Windows 11
 

Well i did a full reinstall and guess what? It fixed the issue so obviously somewhere along the line during the upgrade process a corruption occurred.

Re: Windows 11
 

glad you are sorted now :)
