Hi @ayuobzangivan,
You will need to install OpenStudio 3.0 / EnergyPlus 9.3 directly on you C drive. Then it is not going to interfere with the other versions of energyplus installed. You can read more about why here:
Openstudio 3.0.1 can be downloaded here:
It automatically installs energyplus 9.3.
Hope this will help you.
