Doesn't PF work in 1.6.1 without an Update?

That will not happen. Have you look how old this thread is and when @Mike-NZwas lastly here? It`s more than 2 Years.

Ariane is removed from Tantares long time ago. @WellGood work at the new parts. I love them.

@DrakenexWhich Maintank is this? It looks not like the one of reDIRECT. Or did you modify it?

What do you mean with KSS? Kerbal Space Station? Kerbal Star System?

Link is on page 1, a few posts under OP:

As you can see: no. It is a very old thread and @artwhaleywasn`t here since April 2018. But I tested it in 1.5.1 and it works partially.

Write your own RO-configs or ask in the RO-thread.

Have you test it with RO 1.4.5? Is anything not working? Otherwise the versions says nothing if it will work or not with the specific ksp-version. It is only a number in version-file. Mostly it can be ignore.

Do you have RSS/RO installed?

Then ask in the thread of MLP. But I can say: there is a official build and a dev-build. for the shuttle, I think, you must download the dev-version. Also: there isn`t a one-part-launch-tower. You must build it yourself with the parts.

You must merge the files. So it is correct to replace the parts. They will not be deleted, the will be replaced.

Why update? The launchers and MIR works. Only BURAN has some problems as far as I know. But there is another mod which took over DECQs Buran:

Then ask the RO guys. This mod doesn`t support RSS/RO originally.

Here you go: DPAF (like it was used at Delta II): Old but works. Also this mod has a SYLDA like it used with Ariane 5: The old Lionhead-mod had it too but is quiet old.
