Can vray.exe in RT for 3ds Max folder be used as SA?

V-Ray V-Ray for 3ds Max General

Do we need to install Vray Standalone on machines that have VRay for 3ds Max installed? There is a Vray.exe in the RT for 3ds Max 2018 for x64 folder. Is that the same?

Seems to be running smoothly and frames are matching.
