It's always this way. Adobe upgrades install the new version in parallel withthe old so you can continue to use it while you transition. When you upgrade, you are upgrading the license. You cannot sell or give away one part of the upgrade chain without transferring all versions.
It's too bad you uninstalled CS5, at least for ID. CS5.5 files are not directly backward-compatible so if you need to collaborate witha CS5 user at any point you will need to export to .idml for them to open your files.
I uninstalled CS5 coz I don't want them to conflict each other.
Yeah, I export to .idml file, which is much smaller to email around anyway.
Thanks for the reply.
That's one of the nice things about Adobe -- except for Acrobat, which does uninstall earlier versions, there's no problem with version conflicts.
