I have a Windows Server 2012 R2 with a Perc S300 card in it and I need to upgrade the driver on it. I am trying to install this one, SAS-RAID_Firmware_RPCKX_WN32_2.0.0-016600193000_A06, but I get a prompt saying that "The Update Package is running on an unsupported new operating system. Do you want to continue?" I'm afraid to install the drive as this server has a lot of important shares on it. Can anyone confirm that I can go ahead and install it?
