Sorry didn't have too much time earlier,
But just to offer some more information to those who are having the “simple” version of this issue.
One can trouble shoot it easily.
Typically it seems to stem from a corrupt install of “apple application support” (or some component of).
When I said “install PD with quick time”. And then “update” quick time. What I meant is actually install the full boat PD including QuickTime. Then go to apple, download the latest QuickTime install and allow it to “remove” the previous install and reinstall itself entirely (repair/modify will not work to solve the issue), where by reinstalling “apple application support”. I assume one could likely skip the PD QuickTime installation and just do their own QT installation after but this I have not specifically done.
So.
**To reproduce the issue on a PD installation that’s not experiencing the problem (assuming QuickTime was installed) one can go into the control panel and uninstall “apple application support” and you should receive the error from that point forward when starting PD.
If one is already suffering from the issue its easy to confirm the source of the problem by going to the control panel to see if “apple applications support” is installed. If not then there's your problem. If it is installed then uninstalling QuickTime completely should at least allow PD to start without error. This too will confirm the issue.
If that’s the case then you simply reinstall QuickTime in its entirety allowing it to remove the initial installation first.
This for me is 100% percent reproducible on windows 7 64 bit systems. (although I am not certain windows 7 or the fact that it’s a 64 bit system are relevant to the issue).
Im inclined to think that the QT install included with download version of PD is possibly corrupt and/or mildly damaged.. Either that or the qt install included with PD is just outdated and not handled well by 64 bit systems. I have not checked that personally. I have only solved the issue then moved on.
