Can't open up My MP4Box right after installation

[mahogany]

I have downloaded and installed My MP4Box program which I can't open it up. I see the icon on the taskbar and even when I click on this still can't open up. Tried that many times with no results. I uninstalled and reinstalled My MP4Box a couple times and still no changes for better. I had even installed some older version of My MP4Box and had still the same problem. Sounds like it is incompatible with my OS (Windows 7) or something. Anyway, what's wrong with that bitch

EDIT: I did a scanning of Windows Registry by RegCure and still no changes.

MP4Box is a command line tool. To open up a command prompt:

Then navigate to the directory/folder where you have your audio/video files to mux, and do something like:
MP4Box.exe -add video.264 -add audio.aac movie.mp4

If you'd prefer to use a point and click program, you could try My MP4Box GUI.

Yes, that's what I'm using My MP4Box GUI.
BTW: About CLI I've got no clue at all.

Where did you download My MP4Box GUI from?

On the official site, it mentions .NET 3.5 is required:
http://my-mp4box-gui.zymichost.com/download.html
but Windows 7 should have that as standard.

I'm wondering if it's a compatibility issue between Windows 7 (64bit) and My MP4Box GUI (32bit) - although Windows should work with most legacy 32bit programs. Someone who uses Windows 7 would have to advise you there.

I had the same problem -- then you mentioned 32 bit / 64 bit compatibility. When I installed it, it installed in Program Files, not Program Files (x86) where 32 bit programs go. I changed the install directory to that, and the problem was solved. Weird that it worked at first.

I didn't pay attention then to which folder installation went to. Anyway, a few months ago I had to reformat the hard drive for some reason in my computer. I reinstalled the programs I needed and among other things also installed My MP4Box again. I can open My MP4Box up now. And works with no problems ever since.
