need to upgrade the Powershell 4 in 2008 R2

I have installed the dot net 4.5. & Windows Management Framework 4.0 Preview but still powershell version is showing 2.
Also installed the PS ISE from feathers but no luck still showing the below result.

PS C:> $host.version.major

Any additional step?

The final product is now available

Maybe this will help?

I use $PSVersionTable I’ve never used the one you are showing.

You should use $PSVersionTable. There’s a difference between the version of the host application and the version of the PowerShell engine; you only care about the latter.

Pls see this.
PS C:> $PSVersionTable

Name Value

CLRVersion 2.0.50727.5420
BuildVersion 6.1.7601.17514
PSVersion 2.0
WSManStackVersion 2.0
PSCompatibleVersions {1.0, 2.0}
PSRemotingProtocolVersion 2.1

How to get PS vesion 4? Please

Installed dotnet 4.5.1. Pls see the below snap.

What version of the OS is this computer running?

if $PSVersionTable still showing that then your install did not succeed. Make sure your OS is supported by the Management Framework.

From the bottom of the download page it sounds like only Server 2008 R2 or newer is supported for 4.0.

We acknowledge that there is still a need for management of Windows Server 2008, and Windows Management Framework 3.0 remains the answer for Windows Server 2008.

Boe Prox just posted this this morning as well. Further proof that Windows 2008 RTM and older OSes may not be eligible for W M Framework 4.0

The articles about this are rolling in as we speak. . .

This one may help!

Thanks a ton. Vern you made my day :). Issue got fixed.
