I've tried all of the troubleshooting steps on the page. No matter what I do, I get the following error:
Could not open key:
HKEY_LOCAL_MACHINE\Software\Classe\QuickTimePlayerLib.QuickTimePlayerApp\CLSID. Verify that you have sufficient access to that key, or contact your support personnel.
Can someone please advise me?

Raeyin, have you tryed this? From within the registry, right click on, QuickTimePlayerLib.QuickTimePlayerApp, and go to Permissions. You need to give Full Control to whatever user account you're logged in as. You'll have to be a computer administrator to make that change.
After right clicking and going to Permissions, click on the Advanced button on the lower right, and then the Owner button at the top. That will show you who the current administrator is for the item. And should show any other computer administrators on the computer.
Well, that's interesting. When I tried that, it said, "Cannot Open QuickTimePlayerLib.QuickTimePlayerApp: Error while opening key." Then when I right clicked and went to Permissions, it said, "You do not have permission to view the current permission settings for QuickTimePlayerLib.QuickTimePlayerApp, but you can make permission changes." So I tried to make permission changes, but it repeated, "Cannot Open QuickTimePlayerLib.QuickTimePlayerApp: Error while opening key." Is it corrupt? Should I try to delete it?
I doubt it is corrupt you could try to delete it but that will probably cause a problem with QT. What is the turn of events that took you to the registry?
This is a permissions issue. What account originally installed QT? Are you an administrator account? You need to take Full Control or Ownership of the item in the registry or QT with a administrator account. Whatever account you're using, now, either is not an administrator account or it is being denied permissions. At worse I would think you might have to create another administrator account to take ownership and full control. There are at least 2 on the computer now.
This is a hand-me-down computer from my sister. I assume she originally installed QT, but her account has been deleted. Mine is now the only admin account.
Raeyin, this might be easier to follow than how I'm trying to explain. This is for XP but just go to the top right to look up whatever OS is on the computer, basically it should be pretty much the same.
