I have created a setup for one RDO project using InstallShield, and it seems to work fine. Unfortunatly, it isn't ready for distribution yet, so I don't know how it's going to react on another person's machine. However, I did check with someone else familiar with RDO, and they said that it contained all the proper files.
As far as being a supported feature, that's hard to say. RDO will work in any Version of VB (Learning, Professional, Enterprise). It's just a matter of having the license files for the component. Most of the license files are not included with Learning. However, it's been my experience that when a component is not supported from one version to the next, it won't even be available for insertion into a project without displaying an error message. Probably the best way to test this is to create a simple project that just opens and closes a database with RDO. Create a setup and install it on a machine that doesn't have anything of VB on it. If it runs, then you know it works.
