When I try to run the software the command prompt window opens up and after some time the command prompt window closes and esim panel doesn't open. What can be the reason for this problem?
Most likely because one of the dependencies is not installed properly.
Open command Prompt -> type cd C:\FOSSEE\eSim\src\frontEnd
Then run python Application.py
Post the screenshot of the command prompt. And make sure you're using the latest version
