I am having a problem with megui. It is erroring because it does not have aften and ffmpeg. I tried to use the update feature on megui but it says it cannot open the zip files to install.

When I click on the aften link it brings up the binaries for win 32 and win 64. I do not know what the difference is. I believe I am win 32. I downloaded it and opened it with winRar but there are numerous exe files listed. I do not know which I am suppose to use. When you click on the .exe it just opens a black box for a split second. Is it suppose to do anything else??
