Azure Active Directory-Module : Import-Module : Could not load file or assembly file:///C:\Windows\system32 \WindowsPowerShell\v1.0\ Modules\MSOnline\Microsoft Online Administration Automation PSModule dll or one of its dependencies. This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded

while , I was trying to make one account password never expire, I was trying to connect to azure by using the AAD powershell command utility.
when I open AAD powershell tool I got below error "Azure Active Directory-Module : Import-Module : Could not load file or assembly file:///C:\Windows\system32 \WindowsPowerShell\v1.0\ Modules\MSOnline\Microsoft Online Administration Automation PSModule dll or one of its dependencies. This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded".
when I check the version of powershell, it was 2.0, but the above needs 3.0.

Hence download 3.0 from https://www.microsoft.com/en-sg/download/details.aspx?id=34595 (do as per 32 or 64) and install and then try to connect.
