What is the brand/model/settings for the camera that recorded your .mov video that you are trying to import into Premiere Elements 11 on Windows 7 64 bit?
How are you attempting to import the file into the project - from hard drive save location, from a USB camera to computer connection, other?
What is your specific Add Media/ choice?
Let us start here and then decide what next.
I am having the same problem:
I am also attempting to import a .mov file with Premier Elements 12.
I am running Windows 8.1 (64b) and have no idea what Quicktime version I have.
As you found out, you need to have QuickTime installed on your computer with Premiere Elements, especially

QuickTime requirement can be found in the Adobe published System Requirement for Premiere Elements.
You may find the "View Video Files" in the following Adobe Elements Organizer document interesting as it relates to QuickTime install.
