Q: QuickTime Pro key in Windows registry

I would like to identify where the registration key and other info needed to re-register QT Pro 7 for Windows are stored. Are these written to the registry or stored elsewhere?

With the recent news of support ending, we are planning an effort to uninstall QT on our Windows machines. In the uninstall script, I would like to look for QT Pro registration info and back it up prior to uninstall.

Any pointers appreciated. Thanks.
