Install Devolutions Gateway side by side method not found

When installing Devolutions Gateway on the same machine as Devolutions Server (side by side installation), this error can trigger in the installation logs.

Method not found:'Void System.Management.Automation.Runspaces.InitialSessionState.set_ExecutionPolicy(Microsoft.PowerShell.ExecutionPolicy)'.

Solution

As Devolutions Gateway requires at least PowerShell version 5.1, please update PowerShell to that version to fix the issue. Then start over the Devolutions Gateway installation.
