The software?
I don't see why not as it's free to download.
Now, if you download a collection....I don't know if it's just the one file which you can copy around.
Try it and see.
Download the free collection, and then see if you can move THAT file to your other computer and have it work in EQB over there.
Then you'd be able to link it to both versions of EQ7 (if you have it).
I'm not sure, though, that it's doable.
Let us know.
