I had the previous version of FInal Cut Studio and just purchased Final Cut Studio 2. I chose to uninstall Final Cut Studio first by dragging all the studio programs to the Trash figuring I didn't want to chance having two versions of Final Cut Studio on my computer.
I then went in to install Final Cut Studio 2. It allowed me to install the items such as Motion Content, LiveType, Audio Content, Studio Pro, etc. The option for selecting Final Cut Pro was greyed out and said skip. I don't know why but it's like it already thought it was on there and would just upgrade it. I tried it several times but always had this same set of options.
I went on then and did an install of Final Cut Studio hoping that when it came to installing it would actually work right. Well it installed all the supporting programs but not Final Cut Pro. How can I properly install the whole suite?

re-install Final Cut Studio, and then install the upgrade on top of that.

There was no need to remove the original apps before installing the upgrade. The upgrade installer runs the same as the retail installer, it just requires a serial number for a previous version of FCS. Also, just dragging the apps to the trash doesn't fully uninstall studio, there are many supporting files, frameworks, and codecs that are still left behind. So only removing some of the files can mess up the installer, as you are experiencing.

Take the advise posted above and see if that works, if that fails, run a Google search for an app called App Zapper and use that to remove Final Cut Pro, then try rerunning the installer.
