I'm doing a fresh install of Hyper-V Server 2012 R2 Core in a UCS environment on a B230-M2. The OS is installed and networking is complete. Windows MPIO is installed and enabled. I've downloaded ONTAP DSM 4.1P1 (ntap_win_mpio_4.1p1_setup_x64.msi) but am immediately presented with "No Powershell Installation was found. Data ONTAP DSM for Windows MPIO requires powershell v2.0 or later. Please download powershell and retry the installation." when attempting to install it. This OS is running Powershell 4 natively, so I'm not sure how to proceed. What do I need to do to get the install routine to recognize the presence of powershell? Or is there something else at play here? Thanks...
