The installer will by default put CS5 in a totally new folder.
This is very useful because many users find it better to have the previous version available in case of problems with CS5. These do occur regularly.
You can remove CS4 when you are completely happy with CS5.
You don't need to uninstall or deactivate CS4 before installing CS5. The installer will make a separate folder. The two versions can live comfortably side by side, and you very well may regret dumping the older version if something in CS5 does not work as you expected and need to go back to CS4 for specific tasks.
>Yes deactivate CS4 prior to install. Check this
Yesterday, I deactivated CS4 and installed CS5 Master Collection with Acrobat.
This time, all were successfully installed.
When I checked Help file, I see "deactivate" menu.
I understood that "deactivate" means my CS5 is now activated and registered with Adobe.
Is that correct? Hummer
Even after activation you will have to register by creating Adobe ID as a new user wherin u have to furnish your datals and then enter Products for registration.Once the serial Number is regd aganist ur name your licence will be your asset and is again resaleble and Adobe will incorporate the transfer oflicence.
During the installation of CS5, "Sign In" page popped up.
So my Adobe ID and PW were typed in.
I assume that the sign-in is equivalent to the regisration.
Is that correct?
