Windows 10 and Quicktime

  • I have downloaded Isadora to a new Windows 10 computer and when I try to start the program I get a message that says Quicktime needs to be installed. I installed the quicktime player 7 but iThe Apple site says it is only for Vista or windows 7. So Isadora won't open on the computer. Is there a fix for this or have I downloaded the wrong thing.


  • @DusX ? Do you have advice here?

  • To update: I uninstalled the Quick Time and Isadora to start fresh. I then downloaded Quick Time again and also installed iTunes (which I understand comes with the latest version of Quick Time) and then reinstalled Isadora on the Windows 10 machine. When I try to launch Isadora I still get the same dialogue box that says that Isadora requires Quick Time. Is Isadora not seeing Quick Time because it is looking for it in a different location? Everything is installed on the C drive.

    Another issue: I upgraded to 2.1 from 2.05 and find that the Global Keystone actors do not function properly. This is my registered version on my MacBook Pro and they worked as expected in 2.05\. I am running two projectors through Display Link external USB video adapters plugged through a Plugable USB port but don't understand why that would affect the actors in any way. I still get image, just not the global keystoning.
    Thanks, Old_Dog

  • To Update the Global Keystone issue:

    Flip Horizontal and vertical is off
    Settings: CU to ID Link = 0
    Initialize not checked = -100
    Scale Min = -100
    Scale Max = 100
    Top Left Horizontal: Pulls in Top left Horizontal & Vertical towards center
    Top Left Vertical: Pulls in Top Right Horizontal & Vertical toward center
    Top Right Horizontal: Pulls in Bottom Left Horizontal & Vertical toward center
    Top Right Vertical: Pulls in Bottom Right Horizontal & Vertical towards Center
    Bottom Left Horizontal: No Response
    Bottom Left Vertical: No Response
    Bottom Right Horizontal: No Response
    Bottom Right Vertical: No Response
    This seems like a bug but I thought to ask advice before posting a bug report.
    Also, Open Recent is crashing the program but I can open the file by using Open instead.

    Yes, I reported the keystone bug recently, and have tested the fix. 

    It is working as expect for the next release.

    Is there any prevision when the "Quick Time's bug" will be fixed?
