Installing QuickTime - registry key problem

I've uninstalled quicktime & itunes as completely as I can, including following the directions on the apple support site about how to completely uninstall these applications. I don't see any traces of any apple products on this laptop. But when I try to install quicktime now, everything chugs along for a while & then stops with a message saying

"Could not open key: HKEY_LOCAL_MACHINE\Software\Classes\Interface\{02BF25D4-8C17-4B23-BC80-D3488ABDDC6B}\ProxyStubClsid. Verify that you have sufficient access to that key, or contact your support personnel."

When I click on OK, it rolls back all of the install process that has happened to that point.

I tried logging on as an administrator & the same thng happens.

I tried to look at that key in the registry. When I get to the folder labeled ProxyStudClsid & click on it I get "Cannot open ProxyStubClsid. Error while opening key."

Can anyone tell me what the problem is?

 

A link to the exact directions you have followed on the Apple site would be helpful to know what you have already tried, but until then, here are some suggestions:

Does it work in safe mode?

Have you made sure nothing is running at start up?

Have you made sure nothing is running in services?

Have you had a different User set up on this machine that no longer exists on it? If it was installed under a User name that no longer exists you would see this kind of problem. If this is the case you will need to take ownership of the key and assign it to the Administrator account. This should have happened automatically if a user got deleted but sometimes this just doesn't work out for whatever reason.
