[Frank_S]

At what point does the upgrade fail and what happens?

• During the "Installing Repository Service" step, the status changes to "Rolling back action" and the environment is no longer working for NPrinting

Environments Affected:

• February 2019 and earlier versions

Resolution:

Diagnose:
Check version of .NET using powershell

• open windows powershell
• insert command as follows

Get-ChildItem 'HKLM:\SOFTWARE\Microsoft\NET Framework Setup\NDP' -recurse | Get-ItemProperty -name Version,Release -EA 0 | Where { $_.PSChildName -match '^(?!S)\p{L}'} | Select PSChildName, Version, Release | ft -autosize

Verify that you have the correct version of .NET Framework installed for the target version of NPrinting 
https://help.qlik.com/en-US/nprinting/February2019/Content/NPrinting/DeployingQVNprinting/System-req...

• .NET framework: 4.6.2 or higher.
• .NET framework version 4.6.2 is installed when you install Qlik NPrinting Server, Qlik NPrinting Engine, or Qlik NPrinting Designer. The installation of .NET framework version 4.6.2 requires an active internet connection. If .NETframework version 4.6.2 or later is not already installed on a computer without an internet connection, the installation will fail. You must install the .NET framework version 4.6.2 or later on computers without and internet connection before you install Qlik NPrinting Server, Qlik NPrinting Engine, or Qlik NPrinting Designer.If an internet connection is not available on a computer with .NET framework version 4.6.2 or later already installed, the installer will skip this part of the installation

Database issue:

• If the correct version of .NET Framework is installed, then there is likely an issue with your NPrinting database that will need to be resolved directly by one of our R&D team members.
• Your Qlik Tech Support Engineer will reference our internal tracking reference OP-8179 regarding this problem and work directly with you and the R&D team to repair your NPrinting Database
