If a DLL file is accidentally replaced in the bin folder of NetSim, it can be restored by:

  • Copying the original DLL file from another system where NetSim is installed after verifying that the same DLL file is still unmodified. 
  • By reinstalling NetSim after taking a back up of any code that was earlier modified in NetSim Install Directory (Silent Installation is recommended to save time. Refer: How to perform Silent installation of NetSim?).

   

Please refer the article on What are some best practices for writing my own code in NetSim? for further details.
