During installation of eSim software the NgSpice tool is not getting installed. Also while watching the tutorial of installing the software, in the very first window that appears , when starting the installation, it shows that NgSpice installation space required is around 15 MB. But when I start it , it shows 0.0 KB size required on disk. Even I had downloaded again from the website but still the problem persists. Please look into this error ASAP. Thank you for the support.
please paste the screenshot of the error faced.
