Subprocess.Popen() not working when reading file path from csv file

[herwin]

Thanks !

Most now works using the code you mention, but not all.

the csv file has these lines:

C:\\Program Files\\BraveSoftware\\Brave-Browser\\Application\\brave.exe
C:\\Program Files\\Google\\Chrome\\Application\\chrome.exe
C:\\Program Files (x86)\\Foxit Software\\Foxit Reader\\FoxitUpdater.exe
C:\\Users\\zorin\\Documents\\Python Scripts\\test folder\\JavaUpdate.bat
C:\\Users\\zorin\\Documents\\Python Scripts\\test folder\\KeepassXC Update.bat
C:\\Program Files\\Tracker Software\\Update\\TrackerUpdate.exe
C:\\Program Files (x86)\\2BrightSparks\\SyncBackFree\\SyncBackFree.exe
C:\\Program Files\\VideoLAN\\VLC\\vlc.exe
C:\\Users\\zorin\\Documents\\Python Scripts\\test folder\\windowsupdate.bat
C:\\Users\\zorin\\AppData\\Roaming\\Zoom\\bin\\Zoom.exe

The code works fine for all lines, except 2:

SyncbackFree (7)
vlc.exe (8)

if I chose either of these from my menu I get this error message:

Error:
Traceback (most recent call last):
  File "test_csv.py", line 33, in <module>
    mainmenu()
  File "test_csv.py", line 31, in mainmenu
    subprocess.Popen([prg])

    hp, ht, pid, tid = _winapi.CreateProcess(executable, args,
FileNotFoundError: [WinError 2] The system cannot find the file specified

I copied the line from the csv into a command prompt and the programs open fine, so I know the paths and file names are correct.

Any suggestions why these two give an error message and it works for the rest?
