Another gotcha is that there is no checkbox on the webconsole - rollup. Also check out this doc http://community.landesk.com/support/docs/DOC-1662 it has some good info. Are the credentials you logon to the 32 bit console the same as what you are logged into Windows? What security type are you using?
Also you may just be able to bypass the web console and run RC from the command line. This is the premise behind RCR http://community.landesk.com/support/docs/DOC-5151 I have modified my internal version to work with the gateway since the rollup does not support the gateway and I have multiple cores, and I don't want my support center hunting around for the correct core. If you have just one core a simple batch file can work with RC and the gateway.
