so i downloaded forge before and had 50 or so mods and my pc became very slow and it was to the point where i couldnt open minecraft anymore so i reset my whole computer. and i just dowloaded minecraft and wanted to get all my mods back so i went to download forge, (1.15.2 newest version) and i downloaded it and tried to open the installer and it said something like "there is no app to open this file" and i dont understand whats happening becuase you dont need an app to open a .jar file and i did download forge from curseforge no other places and ive tried a bunch of times and this keeps happening. can someone please help me resolve this.
