If you are unable to download Yahoo! Messenger, there are a few simple steps you can follow, in order to get this application. First of all, update your Windows Installer, from this link http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=8483 For Windows XP, install this patch too http://support.microsoft.com/kb/915865 Because Yahoo! Messenger depends on Internet Explorer, you will have to reset your web browser configuration. In order to do that, download and install the latest version of Internet Explorer
and restart your computer. Open Internet Explorer, hit Tools, Internet Options, Advanced, Reset(select select the "Delete personal settings" options also) and OK. Now, download and run the Yahoo! Messenger standalone installer, from this link http://yahoo-messenger.software.informer.com/ If you still get that error, run the program in compatibility mode, by right-clicking on the application and selecting Compatibility and Run this program in compatibility mode. Make sure to mark the checkbox for Run as Administrator.
