  • Try installing 32 bit version. For me it's solved

  • Use 64-bit Powershell, or as @Joy_at_time_of_his_life stated, install the 32-bit version.

    Version mismatch seems to be most common cause.

  • I have a brand new PC and was getting this same error - drove me nuts for hours. Here's how I fixed it.

    I located the file referenced in the error: "Microsoft.Online.SharePoint.PowerShell.ps1xml".
    Right click to view properties.
    Go to the Digital Signatures tab - click the signer, then Details button.

    I immediately noticed the same error in the details that the management shell was giving me...
    I Clicked View Certificate to see more...

    Clicking over to the Certification Path tab showed me what the trusting authority was and hopefully give me a clue as to why... It shows the Microsoft Testing Root CA 2010 which I did not have installed
    You can find out by running CERTMGR.MSC and looking in the "Trusted Root Certification Authorities" folder...

    I clicked the "View Certificate" button again to view this new root cert.

    Right in the view is the resolution to the problem...
    I clicked the Install Certificate button and made sure to select the "Trusted Root Certification Authorities" as the location.

    Hope this helps someone...
