I am trying to boost the framerate of a video and MEgui isn't working.

I am trying to double the framerate using interpolation to make a video look nice and smooth, and I am following this guide: (http://www.spirton.com/convert-videos-to-60fps/).

I have found a few errors along the way however. The first being that when I try to update MEgui, when it reboots it says cannot run updater.

The second problem is that when I download MKV Toolkit and try to run the file listed in the guide (mkvmerge GUI), it is not on my computer, the file in that location is called MKVToolNix GUI.

The third and the major problem (as it is the one that I can't get past) is that when I try to add a video file to MEgui (step 9), MEgui shows an error when trying to open the file. The error can be seen (https://imgur.com/a/24obM7N) (it's the first picture), and then after clicking okay on that error there is nothing in the input  file box, and after a while MEgui will crash (error is picture 2 (https://imgur.com/a/24obM7N)).

I am not sure how to fix this, it is frustrating. Does anybody know how to fix this?

P.S. I am on Windows 10.

Maybe you need  a different video editor.
Is this a movie you made yourself?
Here are some You Tube videos that might describe what you want.

Notice the first example in the list.
Does that fit your needs?

I'm not trying to reduce the flickering, I am wanting to make the framerate higher, like the process described at the top of the guide I linked to. I am not sure what the correct term for it is.

Sorry I can not give you a specific answer.
The terms often used are:
 "Flickering"
 "Strobing"
Changing the apparent frame rate may or may not help. It depends a lot on what causes the problem.
One causers the presence of florescent lights in an venue of a sports event. A simple  change of frame rate does not help.
Some video editors have an option to reduce the visual annoyance.  That is why I made the remark about using another editor.
EDIT:
Here is another You Tube thing about how to reduce the visual annoyance without any increase in frame rate. It uses the opacity settings of a free editor that lets yu offset a low opacity duplicate of the track and merge.
Hen recommends three track merge, but two may work. On a shot video It is a quick fix. Worth a try.

Otherwise, you will spend days trying to understand error messages.
