Hello Dr. Devlin (the original),
At this point Version Manager does not official support RAD 8. We are looking into adding support for RAD 8.0.2 in the VM 8.4.5 patch release.
Having said that, the updates for Eclipse 3.7 that were added to the VM 8.4.4 release (published on November 1st) may work with RAD 8. This has not been tested, but you could definitely try.
Do test, install VM 184.108.40.206 using the default "Local" install type and select "Plugin for Eclipse 3 (rich integration)". Following this installation, install the 220.127.116.11 patch and test the integration from RAD.
Please let us know what you find!
