Itunes was not installed correctly... Error 7...and then some

Not sure which thread you've seen ... there's a couple of different possible causes of an error 7 that crop up for people.

Did the thread involve installing/repairing the latest .NET Framework, as per the following document?

[iTunes for Windows: "iTunes was not installed properly. Please reinstall iTunes" message|http://support.apple.com/kb/TS3074]

Did you get any error messages, or other sorts of messages suggesting the repair install of the .NET framework didn't go through properly, dale?

If that repair install all seemed to go through without incident, prior to the error 7 when launching iTunes, are you also receiving an error message saying that a dll of some sort is damaged? If so, what is the name of that dll?

It's being unusually cryptic for an Error 7.

Usually if the .NET framework is up to snuff, an error 7 indicates trouble with the Apple Application Support installation. But in those cases, usually there's a preceding message about one of the Apple Application Support program files.

On rare occasions (had it happen to me once myself while installing and uninstalling stuff by way of troubleshooting experimentation), the 7 can indicate trouble with one of the other associated programs (like QuickTime, perhaps BonJour). So, perhaps the sensible way forward for us under the circumstances is a complete uninstall and reinstall of all iTunes and related componentry, as per:

If you get any error messages with any of the uninstalls, deletions or reinstall, let us know what they say.

If, however, the process seems to go through swimmingly, does your iTunes start launching without the 7?

🙂 Excellent news. Glad you're up and running again.

This is happening to me now and I was wondering if when you uninstalled itunes then reinstalled if all of your music and movies disappeared or if they were all still there when you reinstalled?
