Issue:  error while installing LiveHelpNow Alerter "The installer was interrupted before LiveHelpNow could be installed. You need to restart the installer to try again." 

Resolution

  1. Make sure you have necessary permissions to install software on your PC.
  2. Try re-installing .NET Framework 4.0 on your PC: http://www.microsoft.com/en-us/download/details.aspx?id=17851
  3. Ensure that the folder where the Microsoft .NET Framework writes temporary application service provider (ASP) files has the proper permissions for the Windows® Service Account responsible for the LiveHelpNow Alerter. 
    C:\Windows\Microsoft.net\Framework64\V4.0.30319\Temporary ASP.net Files
    C:\Windows\Microsoft.net\Framework\V4.0.30319\Temporary ASP.net Files
