What Is Minecraft Forge?
Minecraft Forge is a mod manager and launcher for installing, swapping, and otherwise customizing your Minecraft mods experience.

Thank you. Very helpful. One issue I came across is I downloaded the .jar file to a network drive and tried to install from there, getting the angry java message about URI. Moving the .jar file to my local drive and hitting install worked file.
That’s a common issue—Java doesn’t always like running `.jar` files from network locations due to URI restrictions. Moving it to your local drive is the right fix. Glad it worked! For anyone else running into similar problems, you can always download the latest version from the official OptiFine official site.
Same issue.
