import os
import sys

def find_missing_dll(dll_name):
system_path = os.environ.get("PATH").split(";")

for path in system_path:
dll_path = os.path.join(path, dll_name)

if os.path.isfile(dll_path):
return dll_path

return None

def main():
dll_name = "wow64.dll"
dll_path = find_missing_dll(dll_name)

if dll_path:
print(f"Found {dll_name} at: {dll_path}")
print(f"{dll_name} not found!")

if __name__ == "__main__":

The above Python code defines a function `find_missing_dll` that searches for a given DLL file (`dll_name`) within the system’s PATH environment variable. It iterates through each path in the PATH variable and checks if the file exists. The `main` function demonstrates how to use this function by searching for the “wow64.dll” file specifically. If the file is found, it prints the path; otherwise, it displays a “not found” message.
