I was trying to install Azure using Install-Module Azure in PowerShell. I got the following error:
PS C:\\Windows\\system32> Install-Module A
Since you are using the lower version of PS:
What you can do in your case is you first download the module in your local folder.
Then, there will be a .psm1 file under that folder for this module.
You just
import-Module "Path of the file.psm1"
Here is the link to download the Azure Module: Azure Powershell
This will do your work.
