Whenever I try to download KSPx64-Patch-1.9.0-To-1.9.1, 'Please Select a valid Kerbal Space Program Folder' message shows up when I select a folder to be downloaded , so I can't update it. I googled this problem and followed some instructions, but nothing was changed. Please answer this if you knnow how to fix it, or good at programming. I've been doing this for 3 months....
