WebPlus X7: 64 bit Question

I have just purchased a new pc running windows 7 64 bit os.

I know webplus x7 will run ok on this but will x6 and x4 happily run on same machine.

Also will photoplus x3 run ok as well.

Reason I ask as I want be able to work on websites built in prevous versions as well as build new ones in x7.

If anyone can answer this question for me it would be most appreciated.
