I purchased quick time pro, and attempted to download quick time 7, but it says I have quick time x installed. I deleted quick time x but it still says it is there and will not let me install.

Note: I tried downloadin the 7.7 version online and it did not work.

Installing QuickTime Player 7

In the optional install items-Quick Time is not an option. I am on Leopard.

Then you either:

1) never had QT X installed and could not have deleted it since QT X is only installed on Snow Leopard (OS X v10.6), Lion (OS X v10.7), and Mountain Lion (OS X v10.8) systems or...

2) you are actually running Snow Leopard (OS X v10.6) and not Leopard (OS X v10.5) as you just stated.

Please confirm which statment is actually correct.
