Windows PowerShell snap-in 'Microsoft.Sharepoint.Powershell' is not installed on this computer?

Question

I am new in using powershell, I have been trying to solve this problem for hours and I cant still make it work.

Prerequisites:

• Using windows 10
• Running the Powershell ISE as Administrator

But when I used the "Add-PSSnapin WebAdministration"

Command that I am trying to run:

Add-PSSnapin Microsoft.Sharepoint.Powershell
$siteURL = Get-SPOSite "site"
$sitelists = foreach ($web in $siteURL.AllWebs) {
foreach($list in $web.lists){ $list } }
$sitelists |select * | Export-CSV C:\liststitles.csv

It shows the following error:

PS C:\windows\system32> Add-PSSnapin Microsoft.Sharepoint.Powershell
Add-PSSnapin : The Windows PowerShell snap-in 'Microsoft.Sharepoint.Powershell' is not installed on this computer.

I also downloaded the "iis7psprov_x64.msi", but I don't know how to install it since I cant run it as administrator. and also I have read that, it should be available in the "WebAdminstration" module. When trying to run the file the following error is prompted:

Might be simmlar to this but for windows 10:

Add-PsSnapin WebAdministration in Windows7

Answer 1

To work with SharePoint online, you need the SharePoint Online Management Shell PowerShell module. Once installed (on your Windows 10 machine), PowerShell will automatically load the commands you need (like Get-SPOSite) without needing to import the module manually.

You can download it from the link above, and an introduction is here: https://learn.microsoft.com/en-us/powershell/sharepoint/sharepoint-online/introduction-sharepoint-online-management-shell?view=sharepoint-ps&redirectedfrom=MSDN
