Exchange Online PowerShell Module Error: Application Cannot be Started – Contact the Application Vendor

While doing a workshop about PowerShell for Office 365 recently, and working with the Exchange Online PowerShell Module, which is needed to authenticate to Exchange Online with MFA , a lot of my students have hit the following error: Application cannot be started. Contact the application vendor.

Exchange Online PowerShell Module Error: Application Cannot be Started

Even if the Details tab don’t say much, this is an easy fix! This is happening only when downloading the Exchange Online PowerShell Module by using Chrome or Firefox, so the fix is simple: Use Internet Explorer to download the Exchange Online PowerShell Module! That’s it!

my problem was Powershell.
A Powershell console was open, therefore a process of Powershell was active and was interfering with the installation.
After closing the Powershell console (or killing the process) the installation succeed.

I was getting the same error, I wish I knew the solution, not it has developed the 2nd stage, where you start it, it runs something on console and disappears. Tried removing and fresh install on IE, still no luck, any ideas?
