Trying to install an application that use 32bit on a 64bit OS

Hi

you have many options:.

1) How to Run a Program in Compatibility Mode in Windows 7:

or

2) How to use Windows XP Mode in Windows 7:

The applications installer must support installing on a 64-bit machine.  You might check with the software company for an alternate installation file or newer version.

You could also install it in a Virtual Machine (XP or 7).  If you have Windows 7 Pro, Ent, or Ult, then you are entitled to a fully-licensed version of XP to run from within Windows 7:

Not sure if you would consider this option but have you tried creating a virtual machine that is 32bit to run the app on.  That is if the other above solutions don't work.  I have had to do that before to run a legacy product on a new system.  

I have used a product like OracleBoxto set up my virtual machine.  Works pretty well, is a small install and pretty easy to setup/configure.:

Kid ... do you mean VirtualBox (by Oracle)?  I also use this for most of my VM's, as it 1) will support 64-bit VM's where Virtual PC's won't, and 2) has more features than VMWare Player.

If you do use a Virtualization software other than Virtual PC with XP Mode, then you must have a valid/unused Retail license for XP or whatever OS you are running.  XP Mode is fully licensed, so there is no need to purchase or use a Retail copy.

Yes i mean Oracle's VirtualBox.

Yes i agree, you need a valid windows licence to load and use any MS software.

I've installed the XP Mode in my win 7, and it works .
But this VM is pretty slow.
Anyway, i guess i'l need to work that way.

tnx u all.

You are welcome!
Now you can give points and close the question.

Glad you got it working ... even if it is slow.
