Can't run any version older than 1.17 [closed]
Solution 1:
This sounds like it could be an issue with Java - 1.16 and below use different versions.
Using Java 8 should fix your issue.
First, download the zip/tarball variant of Java for your operating system from here.
Next, extract it somewhere.
Update the installation's Java path to point to "bin/java" in the folder.
Alternatively, you can use MultiMC, which makes it easier to manage Java versions.
