Why do I get a .NET error when installing the JAI SDK on Windows 10?

To use JAI SDK .NET Framework 3.5 (or earlier) is needed.

Please have your Windows 10 installation media ready. Usually this is a DVD, and you will have to insert the disk into your PC.

  • Open the Windows 10 DVD
  • Copy the "sources" folder from the DVD
  • And past it to the C drive on your PC.

If you don’t have the Windows 10 installation media, please download the latest ISO of Windows 10.

After you downloaded the ISO:

  • Right click on the ISO-file
  • Select “Mount"


  • A new window appears
    • Copy the folder “sources”
    • And past it to the C drive


  • Run the CMD shell as an Administrator and insert the command below:
    • Dism /online /Enable-Feature /FeatureName:NetFx3 /All /LimitAccess /Source:C:\sources\sxs
