Frage von scrooge:
Salü together 
 I use the program for years Pinnacle Commotion Pro 4th 
 So far there have been no problems. 
 The program requires an installed Quicktime. 
 For various reasons I wanted to now of Quicktime Quicktime alternative to change and have it installed. 
 Unfortunately, Commotion but it does not cooperate. 
 So I uninstalled Quicktime Alternative and then again the normal re-installed Quicktime. 
 Nevertheless Commotion will not start. There is the message "This program requires Quicktime 4 or later" and then it quits. 
 Somehow has Quicktime alternative left or what have always synonymous ....... * * grübel 
 Has someone an idea?

Open registry (Start-Run-Regedit), then the branch 
 HKEY_LOCAL_MACHINE / SOFTWARE 
 search. Below there is a "folder" which is either "Quicktime Alternative" is or the name of the manufacturer to pay (then the "QA" folder content below). 
 The complete QA branch can then be gone.  
Note: In the registry you need to know what you're doing. An UNDO does not exist, changes are effective immediately.
