Please help me change the code, why can't the expected effect be achieved after generating the exe?

File download transfer is no problem, the registry is also no problem, just can't play that wav file, what can I ask?

Thank you

mciExecute "play C:\WINDOWS\system32\demo.wav"

Are you sure you can write like this?

Strange, I'm fine here
See if the wav file is broken
When you run to mciExecute "play C:\WINDOWS\system32\demo.wav", is there an error prompt? This function is special, if there is an error, a dialog box will pop up, otherwise it means the operation is normal.
You try to execute this sentence alone (the path in the parameter of this function must be in 8.3 format).
If that doesn't work, try the sndPlaySound function
