A newer version of QuickTime is already installed.

Same error message. I have cleaned the registry, uninstalled QuickTime, emptied temp folders and recycle bin, deleted Quicktime folder from Program Files, downloaded both Itunes8 upgrade and Quicktimes 7 and still the error appears. How can I have a newer version installed when I just downloaded the latest version?

Prior to upgrade itunes was working just fine. Now it isn't working at all. Lesson learned: If it is not broken don't fix it.

This is a long shot but it worked for me. I found it at Free-codecs.com after I ran a Google search on the QuickTime error message.

Quick time alternative 2.7.0

After installing this I reinstalled Itunes 7.7.1.11 and so far everything is back up and running.

good Luck!

I have used the quicktime alternative on the last build and it worked for me. The problem arose again when the software did an update, which was required in order to update the phone.

I had the same problem once, and I think it was because I installed another codec package also capable of running Quicktime. It seemed that Quicktime recognized the codec package as a newer version of it self. When I removed the package and reinstalled Quicktime it seemed to work again...

I must admit that Im not completely confident about this - maybe I accidently did the same as bktx suggests.

I can get the package with my custom mst file to install if i manually run it via command line. If i then add it to SMS for deployment, which runs under the system account it thinks it has a newer version installed. if i run it under the user context from SMS it also thinks there is a newer version installed. When building a brand new pc with only XP SP3, Office 2003 SP3, Media Player 11 and the latest flash player and shockwave player, it again thinks there is a newer version installed. I was able to get it to install under the user context via SMS by removing the Launch Condition sequence from the msi's execute table. This however is not wise as if there is a newer version installed it will attempt to overwrite it in future. Even though removing that condition allowed it be installed under user context from SMS, it still fails when running under system account for new builds. This is very frustrating and there seems to be no way to get an answer out of apple.

I managed to get itunes 8 working - needed the microsoft windows install clean up

1. Uninstall current version of itunes (add/ remove programs)
2. uninstall quicktime ( add / remove programs)
3. windows install clean up ( remove quicktime)
4. restart
5. install itunes 8

There is no version of quicktime installed. A brand newly built machine with just XP defaults and Office. We cannot use the windows install clean up during a task sequence build as i find that totally unnecessary.

The latest version 7.60.92.0 is doing the same thing. Is there such a thing as Apple Support? If so, why dont they do anything except let you write on their forums.

You can extract the msi from the executable, then import into an msi repacker and allow it to install side by side versions instead of upgrading. Then all you would have to do is uninstall the older version
