So today I got my computer working which I had re-built with completely new parts. I started downloading some programs, for example TeamSpeak 3. I downloaded it as 64bit version, because thats what my computer is, it even says in the system information that it is. After I got it installed I tried to open it but it didn't open, it just shows in the task manager processes for a while. So after re-installing it once and finding out that it wouldn't work, I installed the 32bit version which actually did work, it was pretty weird but wouldn't really care for it so i just went with it. Later this night I got a game installed (Battlefield 4) which did the same thing in x64 mode, it wouldn't start! So again I tried the x86 version which is 32bit obviously, and it did start up. This is so weird and I cannot seem to find a fix for this. Would it have something to do with activation of windows as this is still unactivated atm. I would really appreciate if someone found out what does this mean. It's windows 7 professional. And yeah my computer did work great in 64bit mode with the old parts before rebuilding it, and this is indeed the same windows 7. EDIT: FIXED, WAS BECAUSE OF SERVICE PACK UPDATE THAT DIDN'T SHOW UP AT FIRST
