I’m getting this error running the PowerShell installation on a Windows 7 system. Does anybody know how to resolve this?

Hi,

The PowerShell setup is only supported in the following operating systems:  
Windows Server 2012 R2, Windows Server 2016, and Windows 10 x64

I recommend you going through the manual installation if you want to continue using a Windows 7 system.

Regards,  
Eddy.
