KSP has released an new version 0.20 which has a different directory structure for mods etc. Could we please have installation instructions for MechJeb2?

Ideally MechJeb2 should be adapted to 'just unzip' in the new GameData directory like other 0.20 compliant mods, but in the meantime please could we have the documentation?

MechJeb 2.0.8+ should just be unzipped to the GameData directory like any other 0.20-compliant mod. Have you had any trouble installing MJ 2.0.8 that way?

I've just installed MechJeb2 on another machine by unzipping in GameData, and it works. It maybe an issue with that specific install, or with installing to a different directory.

...either way the MechJeb page should have install instructions to be clear: http://forum.kerbalspaceprogram.com/showthread.php/12384-PART-0-20-Anatid-Robotics-MuMech-MechJeb-Autopilot-v2-0-8

Yes, I've found that if you do that it does not load the parts, but if you copy the .dll to the plugin directory in the root KSP folder it all comes right.

I use the Steam installed version, but the installation is redirected to a directory on a SSD to improve KSP loading time. i.e. not the default Steam directory for my system.

Finally resolved the "Part showing up, mechjeb not working though"-issue. When unpacking that stuff into a steam-installation, right into the gamedata-folder, it's write-protected. Remove write-protection on the mechjeb2-subfolder, and it works.. I guess this really should be noted somewhere. :)
