Hi, I have been playing KSP x64 modded for a long time, and haven't got any major issues. I was going to play today and I had a problem that causes the game to load extremely slow (Happens regularly, but it's not that bad for me) so I did what I do everytime it happens, restart the pc. After that, I tried to open the game and a message appeared saying : "failed to launch the game (unknown error)", so I went to the files and tried to find the issue, when I realized my KSP_x64.exe was missing . I can't play on 32bit because of all the mods I have (Parts, gameplay mechanics, physics, visual enhancements, etc.) And I use and love all of the mods I have. Tried everything! checked for the game integrity, reinstalled completely (uninstalling from steam and erasing the extra folders from the game folder) but still no x64 executable. I don't know what to do now! Without the mods almost all my ships will dissapear, and without x64 I can't play it! Thanks for your attention! Edit: I just installed the game in another computer and the x64 executable is still missing... ?!?!?! What is going on? Is x64 executable missing in an early update I didn't realized? I'm seriously confused right now.
