But, when I try to install it pops up (Incorrect command line parameters windows installer v2.00.2600.0) and will not install. Then I get a C:\Program Files\Yahoo!\Messenger\YahooMessenger.exe This application configuration is incorrect. Reinstalling the application may fix this problem. Like I said I have deleted and reuploaded it several times with the same results. Any help will be greatfully accepted.
