I have Adobe Photosop Elements 9 on my macbook, which I use both in native Boot Camp and in Parallels. I keep getting a window which says "this serial number has already been activated on two machines, please deactivate one of the other machines and retry, or purchase a new licence". The same copy is installed on my home PC. Presumably whenever I switch from Parallels to Boot Camp or vice versa, the Adobe licence check recognises the macbook in its new mode as a third machine, when in fact it is the same BootCamped copy of windows that i am running under parallels. How do I make Photoshop 9 see my macbook as the same machine, whether under Parallels or BootCamp ?
