  • Question

  • Hi Im running SP3 upgrade. On the CAS server I am getting the following error:

    Exchange Server component Client Access Role failed.

    Error: Error:

    The following error was generated when "$error.Clear();

              $fullPath = [System.IO.Path]::Combine($RoleInstallPath, "ClientAccess\Owa\Bin\Microsoft.Exchange.Clients.Owa.dll");

              $appBase = [System.IO.Path]::Combine($RoleInstallPath, "bin");

              precompile-ManagedBinary -BinaryName  $fullPath -AppBase $appBase;

            " was run: "Process execution failed with exit code -1.".

    Process execution failed with exit code -1.

    Any ideas?

  • Hi berket,

    Thank you for your question.

    We could refer to the following steps to check if the issue persist:

    1) We went ahead and removed all the versions of .net using dotnetfx_Cleanup_tool by the following link:


    2) Then we rebooted the Exchange Server and then installed .Net 2.0 SP2 x64


    3) Then we again rebooted the Exchange Server and tried installing the CAS role  to check if the issue persist.

    If there are any questions regarding this issue, please be free to let me know.

    Best Regard,
