Hi!

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.

Please help.
Thanks!

    That's consistent with disk/file damage.

    Let's first try running a chkdsk over your C drive. There's Windows 7 instructions in the following document. Select both "automatically fix file system errors" and "scan for and attempt recovery of bad sectors" or use chkdsk /r (depending on which way you choose to go about things). You should be prompted to schedule the scan to run on restart. That sort of scan of the C drive should take a long time ... if it quits after a few minutes or seconds, something's interfering with the scan:

    Does the chkdsk find/repair any damage? If so, does an itunes install go through properly this time?

    This looks like a bug in the installer, I'm getting the exact same thing. Someone suggested installing quicktime first, then itunes after a reboot. Unfortunately, the Quicktime download seems to be the target of a DOS attack, or else everyone else is doing the same thing...

    Where there is no damage to the disk. Is qttask.exe anywhere on the computer? If so, I believe Windows 7 has a Security tab for permissions to individual files and folders. Have you tryed using that? Also, where a .exe file can be the most damaging to a windows computer, is a Security firewall\virus program, kicking it out
