Installing fails on 2008 R2 (lync) RRS feed

  • Question

  • Hello Guys,


    in my lad i am installing a Lync Server. As req. i installed an blank 2008 R2 (come only in 64 Bit) on my Vmware ESX platform.

    Donwloaded Lync mounted the CD and now i get the message, nope u are nto running 64 bit plz check and fix...

    What can i do? I could install the client, but not the server app.

    Must I install some other roles, not mentioned in the guide or i over read it, to make this work?


    Thx alot!

  • Communications Server supports Windows Server 2008 Service Pack 2 and Windows Server 2008 R2. If you have an existing Windows Server 2008 Service Pack 1 server running, it must first be upgraded to either Windows Server 2008 Service Pack 2 or Windows Server 2008 R2.

    Communications Server 2010 is supported on the following editions of Windows Server 2008:

    • Windows Server 2008 Standard Edition
    • Windows Server 2008 Enterprise Edition
    • Windows Server 2008 Datacenter Edition

    Communications Server 2010 is not supported on the following editions of Windows Server 2008:

    • Windows Server 2008 Core Edition
    • Windows Server 2008 Web Server Edition
    • Windows Server 2008 High Performance Computing (HPC) Edition

    Best regards,

  • this does not realy help that the installation thinks it is an 86Bit system.

    its a blank 2008 R2 x64 OS. Some of the install fieles can be installed like the SQl Server other stat as well that the host is not 64 BIT a bit odd isnt it?


    Error Message:

    The version of this file is not compatible with the verion of windows you re running.

    Check your computers system info to see wherthere you need an x86 or x64 version of the programm.

    ->So Lync is only x64 and an 2008 R2 ENT is also only x64


    What should i do? Any clues for me?

  • What is the Vmware ESX version you are using ?

  • This seems odd, but it's worth checking.  The error definately reeks of a 64bit app trying to install on a 32bit OS.  From a command prompt, run msinfo32.  In System Summary, check the System Type.  It should say x64-based PC as opposed to x86-based PC

  • Wow, the only times I've seen this error on an ESX system is when the virtualization technology is not enabled in BIOS on the physical ESX server.
