I have tried installing it several times but running into the same issue: PRE9 will only open as far as the dialog box to set new project name. Somehow the software will not respond to any keyboard or mouse commands at that dialog box except to mouse click on the X botton at the top right corner, and one other button whose name escapes me at the moment. Nothing happens when I click inside the project name box to try to change the name, or the Browse button to change the path, or another other buttons actually. The only thing it lets me do is close the software.
To clarify: I do get past the load screen. I can click on Edit, then click on New Project, and that's when the bad dialog box comes up.
I have tried installing with the software disk and also from a fresh download from Adobe's site. Photoshop Elements seems to work fine though.
