Whether a software installation on a 64-bit system with Vista uses 32-bit or 64-bit computation?

32bit and 64 bit are two different systems. Due to vast usage of 64bit systems now, the developers and companies are now making their applications compatible for both 32bit and 64bit versions.
Following are three scenarios while installing software on a 64bit vista:
1. You have a 64bit vista and you are installing 32bit software.
-
Normally the software will be installed in a 32bit version and will be placed separately in Program Files(x86) folder. This will use the 32bit computation.
2. You have a 64bit vista and you are installing 64bit software.
-
Now the software will be installed in 64bit computation
3. You have 64bit vista and you are installing software that has both the 64bit and 32bit compatibility.
-
This time, the software will be installed in 32bit compatibility and will use the 32bit computation.
Generally common applications have only 1 executable for both the 32bit and 64bit version of windows but bigger applications like Adobe Photoshop, Sony Vegas Pro 9.0, Adobe After effects etc. needs to be specifically downloaded for a 64bit version.

I think you are somewhat confused when installing something on your computer. A 32-bit software is different from a 64-bit one. They are of different architectures and are intended to be installed on their specific system architecture. If you are not sure which to install, you should know your system first. Check if your operating system is running on the 32-bit side or the 64-bit platform.
You can do this by right clicking on My Computer then selecting Properties. In General tab, under System, where you see something like “Microsoft Windows XP Professional Version 2002 Service Pack 3”, you will see 64-bit there. If you don’t see this information and you only see something like the one above, then you are using 32-bit. If you confirmed that your system is 32-bit then you can only install applications that are also 32-bit. Check the software’s system requirements before installing it on your computer to check its compatibility with your system.
