I recently got this message while updating my 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 antivirus and firewall software, re-register VBScript, and then install iTunes, I have a gateway laptop, model MA3, with Microsoft Vista installed. My anitvirus is Trend Micro antivirus 2007. I am not sure if this is all the information you need. I hope it will be enough to help. Please understand that I will need very specific step-by-step instructions because I am not very knowledgeable about computers. Thanks for all your help.
