I am trying to install quicktime (actually just need iTunes..but then iTunes needs qt), but it fails. There seems to be a problem with the folder C:\Program Files(x86)\QuickTime\ - Quick Time wants to write the file QTTask.exe, but complains that it does not have permission to do so. Same thing happens with \PropertyPanels\PanelHelperBase.qpa
I have tried deleting all Apple programs (in the order suggested in the support forum) and also tried to delete the temp folder. That did not work. I have tried to manually adjust the permissions of the QuickTime folder - no effect.
I have run the installation file with admin rights and with different compatibility modes to no effect.
I consider myself to be an experienced user - able to solve most problems - but now I am stuck. I need some input / fresh ideas on how to tackle the problem.
This is very annoying as I cannot sync iPhone/iPad/iPod while iTunes is not running - due to the stupid (sorry) idea of only have your device linked to one library.
