hello

as the title states, i am unfortunately unable to download minecraft forge.

when i go to the website and download the 'recommended' forge installer, it downloads (as usual), but when i open the file, it asks what file it wants me to open it with.

is this normal, and if so, what app do i use?

and if it's not, what setting can i change to fix this?

i've had minecraft forge a couple years back, and i've been dying to relive the nostalgia once more.

thank you from the bottom of my heart.

best regards,

--ari

Some zip managers like to take control of the .jar file extension away from Java.
Make sure you have Java installed and try running Jarfix once, then try the installer again.

ah!! thank you very much, this helped me 100%. it works. thanks again :)
