support for Hyper-V on Server 2012 R2

hello,

i'm having some issues creating a policy to backup Hyper-V 2012 R2.

i get this error: Error validating Hyper-V machine name. Server failed to list VM's (-1)

could not find any info on the support page related to Hyper-V 2012 R2... does someone know if it's supported or not with v.7.5.0.6?

thanks.
