I'm trying to install an update for Quicktime. I currently have version 7.6.6 and would like to install version 7.7 but when it comes to selecting the drive where I want to install it it says:
QuickTime can't be installed on this disk. This version of QuickTime 7 can't be installed on this disk because QuickTime X is already present.
Just in case anyone is wondering about installing QuickTime 7.6 (not 7.7) under OSX 10.6.x, if they only have QuickTimeX, I did this not too long ago.
You'll need your install disc. Insert the DVD. When the Mac OS X Install DVD window appears, select the Optional Installs folder, then double-click the Optional Installs icon. When you get to the "Custom Install" list, you can pick QuickTime 7.
Once installed, you will find QuickTime 7.6 in the Applications/Utilities folder.
You can plug in your QuickTimePro activation code if you have one.
