upgrading from cs3 to cs5 ext.

[hermit 9]

hello,

dec 20/2010 the adobe site had a sale on, i upgraded from cs3 to cs5 ext. i have deactivated it on the laptop that i have been using it on and want to install it on my xps710

The only problem is that when i try to activate cs5ext the dropdown menue to select the serial number that i want to use for the cs3 is not an option, any suggestions will be greatly appreciated.

P.S, i dont remember the process that the adobe support walked me through when i installed it on my laptop, something to do w/ selecting "trial version", then something else, i cant remember.

Wasn't able to quite figure your problem, but see if this doc helps  you: http://kb2.adobe.com/cps/100/1008779.html

Foomoto is it not accepting your CS3 serial number as a qualifying version?  Could you provide more information about which Creative Suite 3 and 5 products you have?
