I apologize in advance knowing that this should be fairly simple to figure out, but my system says im running a 64bit sual core i5 processor with 4GB of memory so naturally the only way to keep smashing my spacecraft into the Mun and make the debris look pretty is to download mods and then support my feeble laptop with Advanced texture manager (correct name?). Anyway I know what system I am running but my program folder is labelled "Program files x86" and inside my KSP folder it says KSP_x64 Data! Pardon my tech ignorance but this has left me slightly confused, and I just wanted to double check before I download anything that might mess up my game. Its the only game I play and I love it! I never thought I could have fun playing a game that required me to use a calculator haha (for the sake of efficiency). One of the things I love about KSP is that its helping me to learn just a little bit more about computers and how system files are stored and subsequently processed, anyway I tried to look this up and educate myself via Google but I was fruitless in my efforts. Now I seek the help of the Kerbalnaut community and will also name a Kerbal after the first person answer my question! *Disclaimer* by answering this question and leaving your name, the kerbal named in your honor can not be guaranteed safety or ensured they will live to see a second mission.
