I have iTunes 6.0.4.2 and Quick Time 7. It is working fine. May be you should check files associated with Quich Time.
I recently installed an iTunes upgrade, which I believe also installs Quicktime. I'm now having problems accessing video content on some websites, getting a blue question mark where I used to see video content. Has anyone else experienced this issue? Is there an easy solution?
Here are my details:
Windows XP
iTunes 6.0.4
Quicktime 7
Thanks!
