how to change window7 from 64bit to 32bit

HI nourh - Welcome to w7forums

Changing bit versions will require a re-install of Windows.

Before you make such a drastic decision, may I ask why you are wanting to change bit versions?
We may can help you with any troubles you are having.

sorry my english not very good I hope to understand me

Hi nourh

Can you tell us a little bit about your system and which windows version you are using. Plus the names of the programs that are not working. Windows 64-Bit will run most 32-Bit applications.

Things you can try
Turn off UAC before installing older application - Configure Windows 7 UAC
Run the applications in Compatibility Mode - Application Compatibility Mode
If you have Windows Professional or greater there is XP Mode - Windows XP Mode

However to reinstall you will need a Windows install disk. There is no switches or options to select from. The 32-Bit and 64-Bit installs are on separate install disk. You choose which bit version you want by selecting the correct install disk.

I second XP Mode!

It allows you to run your 32bit xp only applications in windows 7. It takes a little bit of setup but it works quite well.

here are some MS sites that talk about it...
