While installing the Adobe Master Collection CS3 for the Mac I got all the way though the first disc and then a blank window popped up, stopping the installer dead. The error, a single blank window where it should be asking for disc two is a fairly common one apparently and is caused by a conflict between Safari 3.x Beta and the Master Collection installer. Now the good news, it’s a painfully easy fix.

First, you have to completely uninstall the Master Collection that you’ve installed so far. You can do this by going to ~/Applications/Utilities/Adobe Installers/Add or Remove Adobe Creative Suite 3 Master Collection. Once done, reboot your Mac.

Second, you have to remove Safari 3.0 Beta from your Mac. You can do this by downloading the installer from http://www.apple.com/safari/download/ and using the uninstall option. Before you do, be sure to copy your bookmarks etc. from ~/username/Library/Safari if you want to save your bookmarks. Once again, reboot your Mac.

Now, once you’re rebooted you are free to install the Master Collection and it will prompt you for disc two as anticipated.

If you want at this point, you can restore Safari 3.0 Beta by installing it.
