Your processor supports 64 bit
AMD Athlon? II Processors
Install 64 bit windows and play the game on that.
If you haven't installed OS before then it will be difficult to get it right. Remove all other HDDs and use a separate hard disk to install. That way you wont accidentally mess up things.
Oh thank god. Yeah I've installed OS before. No worry on that.

I had doubt with this, installing both 32,64 in one drive. Thanks buddy
why both? 32bit is wayy outdated now unless you have some use for certain 32bit specific programs
also I believe you can use a 32 bit license on 64bit and vice versa
Only few old ones such as turbo cpp or some really old programs specifically need 32bit only. 64bit OS can easily run 32bit apps. And yes the genuine license for Windows applies to both editions AFAIK. Newer crop of games usually require 64bit support now
Oh..Okay, am now training on Android development course, so there are two different versions of the Development Studio. Am using 32bit one now, so if both OS can't be installed, I'd have to download 64bit again.
64 bit is the way to go these days. I rarely see people using 32 bit and along that most of the software require 64 bit and those who don't just work fine.
Hmm so I will install 64bit over 32.
Thanks all for replying
