32bit to 64bit with same licence

Ah, but did you read the ways of my error ?

Booting OS's on separate HD's via BIOS Boot Order or BIOS Boot Menu key is the smart way to manage multi-boots.

The error is dual booting two 32bit OS's. Having 4gb of RAM is a good reason to test 64bit on another partition.

I've tested it with my laptop, it's fine.

On my desktop there are installations on two separate disks.
I don't want to uninstall my main partition, ergo I have to have the audio partition 32bit too as I only have one licience.

The point of testing 64 bit on your desktop is to see how it runs on that hardware with 4gb of RAM. This is what you said you wanted to do in OP.

I understand you only have two HD's and want to keep your XP for some sound program that you might think can only run on XP. We can possibly help you with that here. Have you tried installing it in the XP Compatibility modes? Compatibility Mode Try all other modes too.

You can also install 64 bit to a partition to test it up to 120 days by extending the trial period, then we can help you get rid of whichever one you don't want. https://www.sevenforums.com/tutorials...-120-days.html

What XP ?
I said I HAD an XP partition, replaced by another W7 installation, which I'm using for audio.
Rest assured I've had all my audio programs running perfectly well on my main W7 disk, using compatibility modes for quite a long time, BUT it's a 32 bit W7.
When I installed it, after running the beta, RC, and finally the retail version, most of the hardware and audio drivers were 32 bit at the time.

In an ideal world I'd use the same licience for 32 and 64 bit W7, but it's not, and so I'll be using TWO 32bit W7 installations until I have to reinstall everything.
