Software running on Vista 64

Hi All,

The company I work for is ordering some new PCs and they are planning on getting Vista 64 and then upgrading to Windows 7 later next year.

I've been asked by my boss to check and make sure all of our software is compatible with Vista 64. This is mostly multimedia software which has been running on XP.

I was under the impression that all software will install fine with Vista 64, if the application is 32bit then Vista will run that piece of software at 32bit. I was trying to do some research but I couldn't find any hard evidence. I was also trying to look for a software compatibility list but they are all old from when Vista was in beta.

Can someone enlighten me on this? Do I need to go and check all the companies websites to make sure their won't be compatabilty issues?

thanks
