Fixing iTunes 8 installation errors

If you encounter error messages while installing iTunes with/or Quicktime such as “"the installer encountered errors before…" here is a solution for you:
Open iTunes installation file with an archiver program such as 7zip. (File / Open Inside, choose iTunes.exe)

Extract two files from the iTunes8Setup file; QuickTime.msi and iTunes.msi, and save them in a local folder.
(If you have problems with extracting these files you can just download the latest version (8.2.1) of iTunes.msi from here and QuickTime from here)
Open a command prompt window (Win + R), navigate to that folder, and run the following command:

”Quicktime.msi /passive“

After you completed installing quicktime, open command prompt again, navigate to the folder where  iTunes.msi is and run
“iTunes.msi /passive”
command.

That also will save your time from uninstalling AppleSoftwareUpdate, AppleMobileDeviceSupport, Bonjour and MobileMe.

Update: You can find the latest itunes only exe from here.
