Hi,
I just got an e-mail from my University IT security group, that they recommend everyone (at the university) to uninstall Apple QuickTime for Windows, since Apple Ends the Support,

The IT security group also recommend not to use the QuickTime Alternative (uninstallation is recommended), since it hasn't been updated since 2010.
How will this affect WATCHOUT?
I guess if WATCHOUT Display is located in a network with no or limited access to the internet, then the problem isn't that big.
But most WATCHOUT Production is on computers that is being used for other things and might often be connected to internet.
I don't recommend any WATCHOUT customers to uninstall QuickTime, but to think on the risk and wait for Datatons recomendation (and hopefully some replacement).
