2008 isn't supported yet in any shape or form. If it works, "great". If you happen to have one spare for testing in your environment, no problem with logging defects (so we can make sure that this will be fixed or looked at when we do support 2008), but that's about as much as I can help at this point.

Any idea when AV for Server 2008 64-bit will be available?
LDAV is currently supported on Server 2008 x64 with LDMS 8.8 SP2 and SP2A.
