iTunes and Windows 7 64 Bit

"iTunes was not properly installed.If you wish to import or burn CDs, you need to reinstall iTunes."

That usually indicates trouble with the GEAR drivers iTunes uses for importing and burning.

Perhaps try uninstalling the drivers manually, as per the instructions here:

... and then reinstalling the 64-bit GEAR drivers, available from here:

There are no "Gear" files on the computer.

That'll likely be the problem then.

Have you tried the standalone GEAR driver install I linked you to in my previous reply?

It is in the "Remove Programs" facility.

And yet there was no sign of GEAR registry entries or program files on the PC when you went to do the manual uninstall? This is a bit odd.

Do you have some other program on the PC that uses GEAR drivers, like Norton Ghost? If so, which version of Ghost (or the other program) do you have?

This link (from the driver downloads page at GEAR) lists partner companies. Do you have any software on the PC made by any of these companies?

Okay. It seems unlikely then that we're going to stuff anything up by uninstalling that GEAR entry that's appearing in your Remove programs.

Attempt to uninstall the GEAR in your Uninstall a program. If it seems to remove itself safely, try a reinstall of iTunes again.

If you get an error message when trying to uninstall the GEAR, let us know what it says. (Precise text, please.)

... One possibility crystalising in my head. I haven't actually seen it happen before (that I knew about), but given that there was a GEAR entry in your Add/Remove programs, it seems plausible.

Can you check something for me? Do you still have that standalone GEAR installer on hand? If so, does it still give you that "later version is already installed" message?

(Here's what I'm wondering ... the GEAR driver associated with iTunes is normally installed via a DifX mechanism. That normally doesn't put a GEAR entry in Add/Remove programs or Uninstall a program. So that entry in Uninstall a program suggests that a version of the drivers has been installed via a Windows Installer mechanism. In that case, there's a .msi of some description for the GEAR drivers, and one symptom of a damaged .msi is "later version" error messages.)

Bang goes that theory.

Better try ruling out some odd registry/uac/user-account issues.

In Computer, open C:\Program Files (x86)\iTunes\ , right-click on your iTunes.exe and select "Run as Administrator".

Do you still get the error message when launching in that fashion?
