I am trying to install NV and in the the setup window getting message as 'Missing arguments' and I am unable to proceed. (Screenshot attached)

2. Installed LR. At the end of LR installation, NV installation option was greyed out.

3. I downloaded and extracted LR12.60 additional components .

4. I tried to install C:\Temp\Micro Focus LoadRunner 12.60 Community Edition\DVD\Additional Components\Network Virtualization\NVInstaller.exe
