hello Quicktime player cannot be opened
where is quicktime on my system? when I try and play a teaching video a box pops up saying Quicktime Player cannot open file.
What do I need to do?
On what Mac is this happening? What is the version macOS? What is the version QuickTime Player?
What does Invisor Lite say about your multimedia file? (Use the extended report.)
The QuickTime Player application is probably fine. It is probably the multimedia file that may not be compatible, and can’t be processed.
