This Zetadocs technical note applies to:

  • Zetadocs PDF 8.2.239 on Windows 8 or Server 2012


The following dialog appears during installation of the prerequisites for the Zetadocs PDF Client:


This is due to the .NET 3.5 framework not being enabled on the system. This is a feature that is not activated by default on a Windows 8 or Server 2012 system.


Enable the .NET 3.5 framework before performing the install of Zetadocs PDF. To enable the framework, please perform the following steps (note that Internet access is required, or your group policy will need to point to the appropriate source files from the Windows 8 installer):

  1. Go to the start page.
  2. Type in ‘appwiz.cpl’ and press Enter to get to the Programs and Features control panel application.
  3. Click ‘Turn Windows features on or off’. The following dialog appears:
  4. Select ‘.NET Framework 3.5 (includes .NET 2.0 and 3.0)’ and press OK.
  5. Once the feature has been enabled, start the Zetadocs PDF installer and proceed with the installation.


This has been identified by Equisys as a problem with the software versions given above.
