You need to download the 64-bit versions of the software.

example; i buy one game on steam when finish istallation it is in 32bit no in 64 bit

and i can't istall dlc because it requires 64 bit

my winodws 8 is 64 bit

[Sir Asvald]

my winodws 8 is 64 bit

I know.. You NEED to download the software which is either 64 or 32 bit.

how i can do that on steam i cant choose 32 or 64 bit

Can you please put punctuation in your messages?

It makes it very hard to read without it!

32 OR 64 BIT will work. It has nothing to do with your OS. Most of my games/applications are 32 bit and my OS is 64-bit

Windows 64-bit features WOW64 technology, that is Windows On Windows 64.

Without emulation, or translation, or performance reduction, it can run 32-bit programs perfectly fine, above and beyond, under Windows 64-bit.

The reason for this, is 2 things:

-> Windows 64-bit features all files needed for 32-bit programs to run

-> Windows 64-bit features a switch system that redirects calls made by a 32-bit software to 32-bit APIs version

-> Your CPU features backward compatibility support.

On the CPU level, this is what a 64-bit long instruction might look like, from a 64-bit program

[0][1][0][1][1][1][1][0][0][0][1][0][1][0][1][0][1][1][1][0][0][0][0][1][1][1][1][1][1][0][0][0][0][0][0][0][0][1][1][1][0][1][1][0][0][0][0][0][1][1][1][0][1][1][0][1][0][1][0][0][0][1][0][1]

(Each "[ ]" is a bit, they are 64-bit of them)

This is what happens when you run a 32-bit program on your system, this is the instruction the CPU will receive

[X][X][X][X][X][X][X][X][X][X][X][X][X][X][X][X][X][X][X][X][X][X][X][X][X][X][X][X][X][X][X][X][1][1][0][1][0][0][0][0][1][0][0][1][0][0][1][1][1][1][0][1][1][1][0][0][0][0][1][1][0][0][1][0]

As you can see, amongst the 64-bit long box, only 32 of them are used out of the 64-bit.

The CPU detects that, and knows that the instruction is 32-bit, and executes it like everything was 32-bit native.

Because of this, there is no translation, no conversion, and therefor no performance loss.

This ability is allowed by your CPU, as the 64-bit support and add-on/extension of the 32-bit CPU.

So to recap:

-> Windows 64-bit can run 32-bit programs just fine, without performance loss.

-> It can do that because 64-bit Windows has all needed 32-bit files inside itself to provide proper support

-> The reason why you have no performance loss, is that there s no translation or conversion needed, as the CPU doesn't need it, as it can process BOTH 32-bit and 64-bit long instruction.

The reason why Steam gets you the 32-bit version of a game, is because there isn't a 64-bit version that was made.

Keep in mind that 64-bit program doesn't give you performance boost just like that. Yes, the CPU supports newer operation codes to do things faster, mixed with the ability of doing calculation with huge numbers (high precision numbers, usually), with ease, as a 32-bit program, for it to send a 64-bit long number, it needs to do some hacking tricks, and that gets complicated if you are doing operation with the number (which you usually do).

Games uses none of those. The new operation codes are really specific for certain tasks, and doesn't benefits most programs.

What Games DO USE, however, what they DO get from making their game 64-bit, is the ability to use more system memory. Basically, break the 2GB or 4GB (depending on how the game is made) limit per process, and use as much RAM it wants from your system.
