In their recent QuickTime update, Apple added a new DLL dependency to their SDK which unfortunately breaks our QuickTime integration. Until this situation is resolved in a more permanent fashion, here is a workaround to get QuickTime to work again in all versions of Expression Encoder:
;C:\Program Files (x86)\QuickTime\QTSystem\ (For a 64-bit environment) or ;C:\Program Files\QuickTime\QTSystem\ (For a 32-bit environment)
;C:\Program Files (x86)\QuickTime\QTSystem\ (For a 64-bit environment)
or
;C:\Program Files\QuickTime\QTSystem\ (For a 32-bit environment)
