Python win32com.client: What are the syntax to open exe file & activate its window?

[JaneTan]

I am completely lost in using "win32com.client" to open an exe program and run it. I used the code appended at the end, but I get the following error:
 
File "C:\Program Files\Anaconda3\lib\site-packages\win32com\client_init_.py", line 113, in DispatchEx dispatch = pythoncom.CoCreateInstanceEx(clsid, None, clsctx, serverInfo, (pythoncom.IID_IDispatch,))[0]
com_error: (-2147221005, 'Invalid class string', None, None)
 
I am quite lost, and hope someone could assist. Thank you!
 
1st: do I state the exe prog complete file path here?

shell = w3c.DispatchEx('C:/Program Files/FAME.exe')

2nd: is it correct to use FAME to refer to the application here?

shell.Run('FAME')

3rd: For AppActivate, is the argument the title bar of my application?

shell.AppActivate('FAME')

 




Complete Code

import win32com.client as w3c 

shell = w3c.DispatchEx('C:/Program Files/FAME.exe')

shell.Run('FAME') 

time.sleep(5) 

shell.AppActivate('FAME') 

shell.SendKeys("input +""C:\programs\FAMESCRIPT.txt""+{ENTER}", 1)
