Error "a newer version of quicktime is already installed" when you attempt to install QuickTime

I am running Vista as an administrator.  I was running itunes version 8.03 for several months.  When I went to upgrade to itunes 9.x, I started to have problems. the upgrade was unsuccessful.  I then uninstalled quick time and itunes and all the other software Apple via the Control Panel, windows Install CleanUp and also delete the apple key in the registry under the local computer and the current user.  I did a search on the computer and remove all apple, quick time and records of safari.

I have also created a new administrator user and tried to install through this user, without success, exact same results.

When I try to install itunes via the downloaded executable software I get the error «a newer version of quick time is already installed...» »

I spent several hours on the phone with Apple and they indicated that they believe that vista is now a registry entry somewhere for quick time that causes the problem.  They suggested that I contact Microsoft.

At this point, I can't use my i touch and would like to get this resolved as soon as POSSIBLE.

Hello flybydug,

Thanks for posting on the Microsoft answers Forum.

Apple should have been able to tell where, in the registry that QuickTime written in. However, review the information below.

1. go to C:\Program Files and delete the entire folder QuickTime.

2. click on start - search/search - all files and folders, select the hard disk (C :) to look in, type in QuickTime, and then click search / search when list files appear, click right on and remove any that you confirm are associated with QuickTime.)

3. Click Start, type regedit, and then click OK. Click on the + to:

Go to: HKEY_LOCAL_MACHINE\Software
In the software submenu, click directly on the entry of Apple Computer, then scroll for QuickTime, right-click and select Remove.

Note: If you click on the + to the "entry of Apple Computer, it will grow and you should see"QuickTime"which are listed there.

4. exit regedit. It will save their output.

I hope this helps.

Sincerely,

Marilyn
