Hi May be this question does not belong here, but it would be a great help if anyone could help me in this issue. I need to use BeMicro development board but its driver software does not support Windows 7 64 bit. So I have to install windows 7 32 bit. Since my factory default operating system is windows 7 64bit that came with my acer 5741 laptop, can anyone give me some suggestions how to convert this as 32 bit?

Thanks for your time.

This question came from our site for professional and enthusiast programmers.

I'd recommend using a virtual machine for development, but this is only feasible if
- you can afford an additional Windows 7 32bit license
- the interface to your development board is supported by the virtual machine (USB, serial port, ...)

If it's possible, this approach has a number of advantages:
- you can easily backup your dev environment
- you can use snapshots to freely experiment in your dev environment
- using several VMs, you can also keep multiple versions of your dev environment around

Virtualization would be the best option. I would look for an older copy of Windows (2000, XP, Vista) that you may have lying around (not installed on another PC). – Dustin G. May 26 '11 at 14:54

Downgrading your OS seems rather draconian, especially since there are other solutions.

As Frank has suggest virtualisation is the key. Frank correctly points out that you will need an additional licence for the VM if you use a standard VM.

However, if you have Windows 7 Professional or better, you can download the XP Mode add-on (FREE) that will allow you to run your application as if it were on an XP x86 machine. Caveat: there is no definite guarantee that your app will work, but it will cost you nothing to try and seems far better than reinstalling your existing OS.

You read my mind :) – John T May 26 '11 at 14:42
XP mode does not support installation of drivers. He may be able to run the app, but the drivers to control the development board will not work. – Dustin G. May 26 '11 at 14:48
@Dustin G. You may well be right, in which case the VM option is the next best solution. And as you suggest, may be worth investing in a cheap secondhand (retail) copy of an earlier OS. – CJM May 26 '11 at 15:29

Try this if you want to install 32 bit programs on a win7 64 bit o/s..New folder in Documents, copy 32 bit program to the folder and install from your computer. Seems to work most of the time. Close firewalls and anti-virus programs first. I loaded a 16 bit program, but lost a few unneeded features.I have done this all the way back to win3.1
