Kerbal Space Program

Here's a workaround, 'til Squad get around to putting the correct TrackIRUnity.dll in the x64 folder:

Replace the TrackIRUnity.dll in the "Kerbal Space Program\KSP_x64_Data\Managed" folder with the one from KerbTrack 1.2 http://kerbal.curseforge.com/ksp-mods/224254-kerbtrack (it's in the "GameData\KerbTrack\Plugins\" folder).

or

Replace the TrackIRUnity.dll in the "Kerbal Space Program\KSP_x64_Data\Managed" folder with the one from here: https://github.com/medsouz/Unity-TrackIR-Plugin-DLL/releases

Start the x64 version and it's green lights and twisty-turny views all round!

Both options work, up to you which you feel comfy with (downloading the zip from KerbTrack won't make Chrome & antivirus things get scared about just downloading a .dll)

KSP 1.1.3
TrackIR version 5.4.2.27545

Stock KSP doesn't work in 64 bit, works in 32 bit.

Following the instructions above fixes it.

This really sucks, I shouldn't have to do this

Just want to add, that I confirm trackir do not work in kerbal 1.1.3 64bit windows 10.
only work in 32 bit as people already say.

I wrote this in the hope it get notised and fixed ;-)

Thanks for a great game.

Still a problem in KSP 1.2 -- workaround still works.
I know it's low priority, but it's also a 2 second fix: just replace the file -- it's not exactly rocket science (ironic). ;-)

Fixed DLL for 64bit KSP ( https://github.com/medsouz/Unity-TrackIR-Plugin-DLL/releases ) is no longer working, as discribed here:

http://forum.kerbalspaceprogram.com/index.php?/topic/152492-121-trackir-5-not-detected-in-x64-again/

This problem needs new attention, in KSP 1.2.1x64 TrackIR 5 does not work at all anymore, no workaround known so far.

The newest version of KerbTrack (v1.4) now functions again as a workaround in KSP 1.2.2x64.

As originally described, replace the TrackIRUnity.dll in the "Kerbal Space Program\KSP_x64_Data\Managed" folder with the dll from this link: https://github.com/pizzaoverhead/KerbTrack/releases/
