Wanted to add a mod to minecraft, so went to download Forge. I haven't downloaded it before to this computer. Opened it and installed it as directed, and it came up as 1.16.3 - I even checked the versions folder and it has "1.16.3-forge-34.1.0". But when I went to select it as the version in the mc launcher it came up as "release 1.7.10-Forge10.13.4.1614-1.7.10" and when I ran the game it was 1.7.10. How could I fix this/where might I have gone wrong? Cheers
