Has anyone got c++ Builder starter installed alongside delphi enterprise?

Has anyone got c++ Builder starter installed alongside delphi enterprise?
I just added a cpp builder starter serial via licence manager and then installed 10.2.1 using iso.
Installation got corrupted, no bds.exe, corrupted serials and I wasn't able to install delphi until I manually removed all folders and registry entries and the cpp starter serial.
So is the starter edition has to be on a separate machine or I just got lucky?
