Exception when starting MashZone service (Win2k3 64 Bit)

Hello, I'm not sure if MashZone is actually supported under a 64Bit Win2k3-platform; however, I encounter the following exception when starting MashZone 0.9.0 Beta as service:

When started standalone, MashZone runs without any exceptions.

Is that a known issue? Any ideas how to fix it?

Thanks & kind regards,
