So, I was trying to play a .mkv file and they said I don't have the codec. Fine then, I opened codecmanager and they brought up a list of codecs I don't already have, like ffdshow, haali, and other stuff, there were about 7 codecs on the list. I chose to download them all, it took a little time and then the download was complete.
I tried to open the same file and they say I don't have the codec, even though I just downloaded it. I chose to check the codec list again and some of the codecs which I just downloaded and installed were marked as "not installed".
I retried downloading all the codecs again a few times and still, even though the program says that I have downloaded and installed them sucessfully, when I refresh the list, the same codecs which I just installed are there marked as "not installed".
Is there a solution to this?
