Web Reference: Feb 28, 2023 · If your python program that uses os.startfile("File.exe") is not in the same working directory as File.exe, it will not be able to find the file. You can check your current working directory with os.getcwd() and change your working directory with os.chdir(path). This mapping is captured the first time the os module is imported, typically during Python startup as part of processing site.py. Changes to the environment made after this time are not reflected in os.environ, except for changes made by modifying os.environ directly. Encountering the OSError: [WinError 193] %1 is not a valid Win32 application in Python, especially when using the subprocess module on Windows, typically indicates that you are attempting to execute a file that Windows does not recognize as a runnable program (an executable).
