How do I get the upgrade to Xara 17 installed on my second computer? I've had Xara installed on two computers, one stays in the studio and the other travels with me, for many years. After substantial problems, I've been able to upgrade to 17 on the studio computer but I can't see how I can get it installed on my second computer. Also, unfortunately, I didn't save the key (the P- number, whatever it's called) and I suspect I'll need to get that - it isn't on the list of installed programs on the web site, neither is the newly installed version 17.
