Operations Manager 2007: 32 bit app monitoring on 64 bit OS
If you are monitoring a 32 bit app like SCCM running on 64 bit OS, you will need to manually deploy the 32 bit Operations Manager agent to the box. Apparently there are problems monitoring a 32 bit application using the 64 bit Operations Manager Agent. By default the 64 bit Operations Manager Agent will be deployed to the 64 bit OS if you deploy using the Operations Manager console.
