StarTools

I want to add or move my Star Tools across the room to a better computer.

When I look to download it there, all I see is a buy/demo option. Is there someplace to type in license info? On my present computer, it shows my name and address but no license number to use elsewhere.
Do I need to repurchase or, if absolutely necessary, move my license to the other computer? It's silly for me to be processing on this much less capable desktop when
I have a powerful "gaming" computer a few feet away.
Thanks.

I found the email that has my license attached, but it's not a file that opens without some app.

Copy the licence file to the distro folder on the new computer.

Thanks.
Unfortunately, that didn't work.

Didn't work as in 'doesn't launch on the new installation' or you get the 'Thank you for evaluating StarTools' notice?
