I've downloaded the file and the mirror file but all it does it create a shortcut to a program labeled "MM" called MC Modinstaller, when opening this program it goes up only to version 1.12.2 and won't even install Optifine
Strange, here is the direct links encase that works:
https://optifine.net/downloads (Official Optifine site).
Or I send you the 1.14.3 Optifine jar so you can install it which I'll put on my Google drive or Discord. Just let me know and I'll put it there.
