Symptom

When you install iTunes in a computer running Windows Vista, you may receive the following error:

iTunes could not be installed because Visual Basic Script (VBScript) is not installed or has been disabled. Make sure VBScript is installed, turn off script blocking in anti-virus and personal firewall software, re-register VBScript, and then install iTunes.

Resolution

iTunes official knowledgebase states the following:

If you see this error, it may be because the Windows Installer technology is unable to process the Visual Basic Script embedded inside the iTunes and QuickTime Installers.

For more information, read the article: iTunes and QuickTime for Windows cannot be installed without Visual Basic Script (VBScript)
