If you uninstall CS4 you may run into file association problems. THere are fixes but requires some work on your part.

Best advice is if you don't need the disk space is to leave it in place. Can be usefull in cases where CS6 develops problems.

What file association problems have occurred? I too want to uninstall CS4 on a computer that has both CS4 and CS6 installed. I need some more disk space. If there are known problems after uninstalling CS4, what are they?

Curt's right on. The Photoshop CS4 uninstaller can break associations (like double-clicking a .psd file and having it open in Photoshop).

You might be able to correct the problems in Bridge CS6, by using the [Reset to default associations] button in the File Type Associations preference panel.

But if that doesn't work the worst thing you'll have to do is uninstall all versions of Photoshop, then install the latest only. More time consuming, but not a "can't get there from here" level problem.

Some users experience a registry problem where one has to either change the registry or uninstall, run script cleaner, then reinstall.

I haven't yet uninstalled CS4.

I,m under the impression that CS4 must be installed on the machine for a 'upgrade to' version of CS6 to be successfully installed.

Is this assumption wrong?

Yes, it does not have to be on machine. When install asks for qualifying product type in s/n of CS4.

No, but it's not essential since upgrades include the full program code. The serial number differentiates a full version from an upgrade.

If the CS6 ugrade installer cannot find an earlier qualifying version already installed, it will ask you to enter the serial number for an earlier qualifying version instead. You then enter an earlier version qualifying serial and the CS6 installer will continue.

When I'm installing (or reinstalling) Creative Suites where the latest version is an upgrade version, I only ever install the latest version - even if no Adobe software was previously installed on that particular computer.
