Cannot install Azure Active Directory Module for Windows PowerShell. MOSSIA is not installed RRS feed

  • Question

  • On my Windows Server 2008 R2, when trying to install Windows Azure Active Directory Module for Windows PowerShell i got the following error message (although Microsoft Online Services Sign-In assistant version 7.0 is installed) 

    "In order to install Windows Azure Active Directory Module for Windows PowerShell, you must have Microsoft Online Services Sign-In Assistant version 7.0 or greater installed on this computer"

     NB : on  a french server  "Pour installer le Module Windows Azure Directory pour windows PowerShell, l'Assistant de connexion de Microsoft Online Service 7.0 ou version ultérieure doit être installé sur cet ordinateur".

    Tried to uninstall/ /repair / ... Microsoft Online Service Sign-In assistant, but not helped....

  • Maybe thats your solution:


    Somemismatch on dependency check, the Beta-version of the sign-in assistant fixed the problem for me and the guys on the thread.

    Dear Freinds, i am also struggling with this problem i have installed the latest suggested BETA from the link but face the same issue.

    I tried this on This is really frustrating as this has become a challenge for me infront of management.

    Please advise possible solutions, how to get module loaded manually in PS or some other better thing.

  • Same issue here on Windows 8.  What's up Microsoft???

  • The workaround solution is to install instead the Microsoft Online Services Sign-In Assistant for IT Professionals BETA

  • Hello all,

    I too experienced same error but JFYI yesterday I've found that applying workaround described below before installing AADM for WinPS (Azure Active Directory Module for Windows PowerShell) indeed worked perfectly.

    Because others might too dislike to use MOS SIA Beta (Microsoft Online Services Sign-In Assistant build 7.250.4551.0) in their production environments, I'm sharing my solution here to provide such alternative while having MOS SIA RTW (Microsoft Online Services Sign-In Assistant v2.1 but build 7.250.4303.0 when installed).

    A) To temporarily change MOS SIA RTW version copy at least 6 lines below inside Notepad and save file as TempVerMOSSIA.reg, then double click it to merge changes into registry, then install AdministrationConfig-xx.msi (which means AdministrationConfig-fr.msi for Etienne, or AdministrationConfig-en.msi for english readers, for me it was  AdministrationConfig-it.msi)

    Windows Registry Editor Version 5.00


    B) To restore original MOS SIA RTW version just copy at least 6 lines below inside Notepad and save file as RevertVerMOSSIA.reg then double click it.

    Windows Registry Editor Version 5.00


    I hope this can help, like it did for me.

  • The beta fixed MSOL Powershell, but broke Lync my ability to sign in to Lync.

  • Works like a charm!

  • Registry fix worked for me. Thanks for posting it.

  • So here we are 6 months later.... now I'm on Server 2012R2... are we still having to hack the register or run beta in our production? I'm having the same stupid issue....still

  • The "MSOIDCRLVersion"="7.250.4551.0" hack does work but please? What is this? Microsoft?
    mercredi 27 novembre 2013 17:14
  • Registry fix worked for me. Thanks

  • I was through the same pain with Win8 Pro and installed the BETA version of MSOL Sign-in assistant helped.

    On Win7 I don't have this issue and worked with RTW version fine.

  • This is such baloney.  I went through the whole reg hack with the beta version and that resolved the first error message.  Then it said I needed .NET Framework 3.51 SP1 or greater.  When I attempted to install .NET 4 it said I already had that or a higher version on my Win 8.1 PC. Control Panel said it was .NET 1.1 so I uninstalled that rebooted and tried 4 again.  Same message. Then I tried 3.5. That did it.

    Come on Microsoft!  We need these tools to run PowerShell with Office 365.  Why make it so hard?

  • The beta online services sign-in assistant worked for me also.  Server 2008R2.

  • it has always been hard, or fraught with issues. I had to fight with my anal admin, whose (correct) policy it is to refuse to install something that says "beta". Almost sabotaged the whole adopt

    What is interesting is the role of the service, it installs.

    Its essentially a credential store, talking to the STS at the outset so apps, like lync or outlook, might NOT need to wait around on the STS. Similarly, powershell app. This has to "evolve" now, with the whole token store concept for native apps, based on JWTs, and offline access when tokens control DRM-ed content.

    I sometimes feel like its old US antitrust issues that PREVENT microsoft from doing things right, here.

  • Installing the Beta will keep some other applications that use the Sign-in assistant from working.

    We've experienced this with Dynamics CRM Outlook Integration: This component only works with the last RTM release of the Sign-in assistant, not with the newer Beta that is required for AAD PS.

  • .Net 3.51 and .Net 4 are completely different products. Admittedly confusing naming! But they have different APIs so both may need to be installed for different products to work.

  • Thank you kindly.

    Works perfect even without a reboot.

  • Hello all,

    I'm updating again this thread just because I believe that a definitive solution (no more Beta :-D ) indeed already exist for sure for Etienne Bailly (who asked this Q) and for others with Windows 8.1 / 8 clients because of latest 'Microsoft Online Services Sign-In Assistant for IT Professionals RTW' corresponding to version 7.250.4556.0 was already released to web (RTW) a while back (on 2/17/2014).

    P.S. About others with more updated servers (Windows Server 2012 R2 isn't really listed among supported OSes excerpt I'm adding here too) I expect them to get a solution too because of modern client (Windows 8.x) support (while JFYI its install failed when I tried on a Windows XP Professional SP3 I have around).

    "Supported operating systems: Windows 7, Windows 8, Windows 8.1, Windows Server 2008, Windows Server 2008 R2, Windows Vista"

    "Supported processor architectures: x86 and x64 for all supported operating systems"

  • the registry fix method worked for me. seems like a more clean hack rather than putting the beta app and causing other issues.

  • Hi Etienne.

    This does not work for some users. I have that installed and I still get the error.

  • Hi ReliableRick,

    I just uninstalled/re-installed MOSSIA and Azure AD PS module and did not hit any error. In my case it installed MOSSIA v 7.250.4556.0. Can you clarify/confirm what error you are seeing? Is it exactly the same as Etienne's original post? I know the engineering team recently spent time working out various problems with this installation, so very interested to see what might be wrong here.

  • Just install latest version 'Microsoft Online Services Sign-In Assistant for IT Professionals RTW' corresponding to version 7.250.4556.0 and that fixed my issue.
