I downloaded Mc Modinstaller today but it doesn't always work when I want to play the Minecraft version of Modinstaller, Minecraft wears out and nothing happens. I ask for help.
I also downloaded it (and deleted it again), I wouldn't use it, it is quite buggy and a little bit dirty the memory.
If you want to have it anyway, although there are better methods (twitch launcher (curse) or install it yourself), try starting again -> delete versions, garbage clear… And then again a mod that you have previously googled if it it is also compatible and professional to open. If that works you can try several (some mods are also not compatible with each other) and if not then it just doesn't work because of things like the wrong version of the mod or an error from the installer…
So not all mods are functional with this installer and some mods are not compatible. The best thing to do is simply install it yourself and move the mod into the mods folder… There are some good tutorials for that, you will definitely find a video.
Ps: may I know which mods do not work?
