InstallShield 2014 Premier Edition 

In the basic msi package  we use InstallShield pre-defined check for PowerShell by searching the following registry:

HKLM\SOFTWARE\Microsoft\PowerShell\1\PowerShellEngine

Value: PowerShellVersion

This registry entry does not exist in some  Server even though a new Powershell version is installed.

Is there any InstallShield recommendation for this?

Or should I use following advice:

Installation Checks for Windows PowerShell 2.0

You may also have a legacy application that checks for the existence of Windows PowerShell on the box via the registry, particularly for the existence of HKLM:\Software\Microsoft\Windows\PowerShell\1\PowerShellEngine. As long as your application only targets supported versions of Windows and Windows Server (7/8.1/10 and Server 2008R2/2012/2012R2/2016), you can remove this validation altogether.

If not, you should instead check for the existence of the file %systemroot%\system32\WindowsPowerShell\v1.0\powershell.exe. If your installer absolutely requires a registry-based validations, you should first check for HKLM:\Software\Microsoft\PowerShell\3\PowerShellEngine (note the 3) before falling back to HKLM:\Software\Microsoft\PowerShell\1\PowerShellEngine.
