Upgade error: Could not open key: HKEY_CURRENT_USER\SOFTWARE\Apple Inc.\Internet Services. Any advice?
During a standard iTunes upgrade to the latest version (11.1.4 for Windows Vista), the installation failed with the following error message: Could not open key: HKEY_CURRENT_USER\SOFTWARE\Apple Inc.\Internet Services. Does anyone have any advice as to how I can fix this and reinstall iTunes? When I try to open iTunes I get the following message: iTunes.exe. This application has failed to start because MSCVR80.dll was not found. Re-installing the application may fix this problem. When I try to run the installer I get the above error so I'm going round in circles!
