How do I change my KSP version?

[Imanukekaboom]

Hello again.

I have been trying to install a mod called the "Interstellar Expanded" mod (it was something like that).

The only problem is that it won't work with KSP version 1.2.2 and it only works with 1.2.1

How do I downgrade my version by 1?

Extra info- I installed KSP using steam, and it only allows me to go back to version 1.1.3 and 1.1.0, which don't work.

If you mean Interstellar Extended, the thread says it works with 1.2.2.
If you're trying to install it with CKAN, CKAN is probably just being slow (or stupid, CKAN does that). Install it manually.
