Could not link 'vsim_auto_compile.dll' error troubleshooting.

Hi Njoroge, 

Regarding the solution provided in the link, here are some suggestions on how to run it:
1. Command Prompt (cmd)
If you are running the simulation from a Windows Command Prompt or Questa Command Shell, you may launch the simulation using:
vsim -c <module to stimulate> -ldflags "-lws2_32" -64

2. Questa Transcript Window (GUI mode)

If you are running the simulation from the Questa GUI, you may enter the command directly in the Transcript window. In this case, the -c option is not required.

3. Simulation Script 
If you are using a .do, msim_setup.tcl, or run_msim.tcl script, you may locate the vsim command in the script and add the necessary parameter to that command.

Please feel free to let me know if you have any issues or questions after trying the above suggestions.

Regards,
