[#310115] There's a problem with the installation of the .NET Framework (Windows 7 or earlier)

There's a problem with the installation of the .NET Framework in Windows 7 or Windows Vista. Without a properly functioning .NET Framework, Citavi and the Word Add-In will not work correctly or at all.

Solution
  1. Run the Microsoft .NET Framework repair tool, which can be downloaded from the Microsoft Download Center.
  2. Download Citavi from http://www.citavi.com/download or download the most recent beta version from http://www.citavi.com/beta-info.
  3. Start the setup. It will recognize that Citavi is already installed and will proceed in repair mode. Continue through the assistant.
