If we want to install Ansys software again in the system after properly not installing it, do we need to format the system and then need to install it again

I have installed Ansys software in the system but in the download file magnitude is removed as it contain virus, so the software did not installed. Again i am downloading to install it. My friend said I need to format the system, if it is not installed in the first
