This happens if VANET simulations are run as 'Non Admin' users.
It is always necessary to run VANET simulations in Admin mode, preferably under the Administrator user account.
If this doesn't help you may refer the following guidelines to ensure that SUMO NetSim Interface is properly setup:
Both Python and pywin32 are required for VANET simulations to happen successfully. This is essential for interfacing NetSim with SUMO which is a python based road traffic simulator.
- Check if Python 2.7 pywin32-220 is installed in your PC from the control panel.
- If not installed, download and manually install it from the following links based on the system configuration:
- Uninstall any other versions of Python already installed in the system to avoid conflict.
Note: It is always recommended to run VANET simulations in Admin mode, preferably under the Administrator user account.
