Windows Live Installer problems? Try this.

If you are having problems installing Writer, Messenger 8.5 or Mail, in particular if the the Windows Live installer disappearing halfway through (after a Windows Vista UAC prompt if enabled), this may help.

  1. Close all Windows Live applications
  2. Navigate to C:Program FilesWindows Live and delete the Installer folder
  3. Navigate to C:ProgramData and delete both Windows Live Installer and WLInstaller directories if you have them.
  4. Reboot (important!)
  5. Reinstall the application you want to install

This may be an issue if you installed the leak Messenger build, as all Windows Live beta applications need to be the same language. See the Windows Live Installer FAQs for more details.

PS: If someone can tell me what the equivalent for step 3 is in Windows XP that’d be great :)

Update: Apparently step 3 for XP is to go to C:Documents and SettingsAll UsersApplication Data instead of C:ProgramData. (Thanks to DN2004 for the heads up)

Update2: There is now a more official solution to this problem. See our follow post.

Update3: there is also another fix (Thanks MeggarK) which runs as follows:

  1. Reboot
  2. Click START>Run and type ‘command’ to load the console.
  3. Type in:

    regsvr32 wups2.dll

    and press enter.

  4. Type exit to leave the console
  5. Download and run the windows live installer, it should now work perfectly.
