Not sure what ' flop' your 64 bit disk means ?

I have only just upgraded to W72 32 ultimate ... as the Windows 7 compatibility tester advised this was the most complete version of W7 I could install.

I just run tester gain and for 64bit it advise "you will need to install a custom install"

It does give me a link to Dell website - which seems as much use as a chocolate teapot.
I'm assuming my h/w is only 32bit and not going to get the benefits of a 64 bit system.

If a Microsoft application told you that 64-bit would require a custom install, why not do a custom install of 64-bit?

Is this the tool to which you refer:

This is not a RAM question but a question of Address Space. 32bit has an address space of 4GB-1 and all components that have memory or need RAM have to be accomodated in that space.

Even if you have e.g. a GPU with let's say 1GB of it's own memory, it will need the address space from the 4GBs in order to be able to address it's own memory. Then there are a few other system components that need address space or real RAM.

Bottom line: typically a 32bit system with 4GB of RAM will give you 3.25GB usable. But if you have a bigger requirement for the GPU, it can be less.

Here is an article that describes it pretty well: Maximum Memory in 32-bit Windows Vista : Windows Vista and Windows 7 Help

OS: Win 7 64bit. Is it generally not a problem to choose to install a piece of 32bit software outside the win 7 default program folder for 32bit software? Or is 32bit software only supposed to be running flawlessly, if installed in that default 32bit folder? Thanks.
