Problem with SRM5 installation

Hello,

I installed SRM 5 on a vCenter 5 server and the installation went fine. The problem is that I can't see the SRM tab in vCenter and I get this error message :

Call "VirtApplianceManager.IsVirtualAppliance" for object "Integrity.VirtApplianceManager" on Server "MyServer" failed.

Is it a configuration issue in vCenter or should I re-install SRM?

Thank you.

Frank
