We have a problem. We installed LoadRunner 8 (trial version) in the same PC we have installed WinRunner 7.6 (seat license).
Now, TestDirector - Winrunner conexion not run (Before install LoadRunner the conexion between TestDirector and Winrunner run ok).
The errors appears are: "Cannot connect to the TestDirector project"(WinRunner), "The RPC server is unavailable"(Details) and "cannot set mitmatch-break to on during remote execution" (TestDirector)
He have uninstall LoadRunner and Winrunner, and then install Winrunner, but problem continue...
