Network discovery fails in SCOM

I’ve enabled network discovery but nothing is showing in SCOM - only error in the event log is event 157 saying it’s not a valid 32 application? Is this related or is there something else going on (and if so, where can I find out what’s going wrong!)

In the SCOM Console look in Monitoring - Operations Manager - Network Discovery.

There you have two Event views you can look at to see whats going on in the Network Discovery process.

This might help - looks to be the same issue.
