Crystal Runtime Errors

Just curious if anyone has dealt with conflict between Crystal Developer and
Crystal Runtime and how that was solved. I am having an issue with getting
the Crystal Reports Runtime to install correctly on the Epicor 9.05 server,
even though it works and runs on all clients and other servers.

The Crystal developers version was installed, but removing it hasn't solved
the problem and just wondering if anyone else has solved the problem and
would have any suggestions prior to me going mining in the registry to find
out if there are any keys that are causing the problem when not removed
during an uninstall.
