I accidentally made the jar file open with minecraft launcher so everytime i try to open it, it just takes me to minecraft launcher how do i change it back and what should it open with.

im so confuseeeddddd

When I try to download forge I do not find the Icon that it downloaded, but in the bottom of my screen it shows that it downloaded. I open it and it says what do you want to do with it, the three options being save, save as, and open, but all 3 of the options lead me back to the same view downloads - Internet Explorer page where the same thing happens.
