PERC H710P Mini firmware (PowerVault DL4000)

I'm trying to update the firmware on my PV DL4000, and I cannot find the update for PERC H710P Mini.  I'm looking for version 21.3.2-0005, but every version I try says it is not compatible with my system configuration .  OS is Server 2012 x64 (NOT R2).  

I've tried both the 32 and 64 bit versions from here
