I received an error while running Photoshop 3.0 on my Windows virtual machine. I then manually installed Quicktime but the error still appears. What can I do to resolve this issue?
To piggy back on @Jeff Arola question - you need to install the same version of Quicktime that was released when your version of Photoshop was available. Example - Photoshop CS3 was released in 2007 meaning you'd need Quicktime 7.3 etc. Current installs of Quicktime would not be compatible with such old software.
