Nvm, in CMD I opened the wrong version, here's the problem now.
Error occurred during initialization of VM
java/lang/NoClassDefFoundError: java/lang/Object
When I download the jar file of the installer it just doesn't work. CMD said that the file doesn't support 64 bit. Can someone help? Latest version.
Methods tried:
JarFix
Using CMD
Downloading versions behind the latest one.
I was downloading 1.16.3 forge (both recommended and latest version) and had the same error
Failed to run processor: java.io.EOFException:Unexpected end of ZLIB input stream
Here's downloading log (for latest version, dunno where is the log for recommended)
