Installing CS5.5. from a CS4 upgrade
Hi
I am trying to install CS 5.5 Master Collection on Windows 10.
It is an upgrade version from CS4.
I have serial numbers for both.
I have downloaded CS 5.5 and entered the serial number but then it asks to "Enter Serial Number Upgrade"
I then have to select CS4 from a dropdown menu and enter my serial number but I get the message "This serial number is not for a qualifying product. Please try another."
It looks like I need to download CS 4 as well, but it is no longer available from the Adobe website.
I've activated the trial version of CS5.5 and keeping my fingers crossed that it will carry on working more than 30 days, but I'm not holding out much hope.
Please can anyone let me know where I can get the version of CS4 that I need, or any other ideas that you have to make CS 5.5 work?
Thanks
Charlotte
