There version 5 and 6 work great with Win7, Win8 and Win10 any version. They have a 32bit and 64bit version but other than that, any version of Win works great, I have it installed on Win7 ultimate, Win8.1 and Win10. Click on start, right click on my computer and select properties to see what if you are 64bit.
I even use the free version on a couple of my systems as I only need complete images.
