I just bought the Master Collection upgrade from CS5 to CS 5.5 (as part of the deal for auto upgrade to CS6). Are there any best practices I should observe for installing the update to make sure it doesn't gum up or fall over or whatever (or should I just whack the disc in and let it run)???
We're running Win7 SP1 64bit.
CS5 and CS5.5 both can stay on one single machine. So, its upto you, if you would like CS5 still be installed, even though you won't be needing it after installing CS5.5. So, if you want you can uninstall CS5 before installing CS5.5 for saving some additional space or just proceed with the install of CS5.5 and enjoy the software.
Also, as Steve mentioned above, you can Turn off UAC, anti-virus program just to be sure that any of your security settings won't interrupt the application.
Here is a quick guide to Restart Windows in a modified mode | Windows 7, Vista -
Turn off all startup items and in services, just turn off all non Microsoft services.
I have Win7 64 bit and this worked for me. After installing, the problems I had were solved by running some programs in Administrative mode. It was not good enough to run in an Administrative account.
