[QUOTE=richard_g;2280184]I have got a v6 registration key however after installing v6 and clicking the v6 registration key it was not associated with the program (I manually associated it by selecting the program and ticking the box so it always opens files of this type with the selected program).
It was following this that I thought I’d investigate why v5 registration keys where still associated with v5 of the program (even though it had been uninstalled) and why v6 registration keys were not automatically associated with v6 of the program.[/QUOTE]
If I understand what you’ve typed here, I think you are getting the DVDFab registration key, sent to you by email when your payment was rec’d, and some of the various items in the O/S registry (two totally different things) confused.
The registration key for DVDFab doesn’t need to be associated with anything - all it does is write some values to the O/S registry that enable the full version of DVDFab for you. (and that’s only a one-time event - at least, until a new version is introduced, and new keys are required).
The registry values you are still seeing associated with DVDFab 5 (and other programs) are not removed by the un-install process. If, however, you change a file association (such as change VOB to Fab6), the O/S registry will automatically be changed, and selection of that particular file type will always cause DVDFab v6 to be loaded. (Not always great, when all you want to do is watch a ripped file on something like VLC Media Player, to make sure it ripped OK).
File associations have to be done manually by you, as the O/S has no way of reading your mind to know which file types you want associated with which programs.
Have I understood your comments correctly?
