You have more than one problem. Firstly, as you have detected, the
Windows command interpreter's parser has to be steered away from the
spaces. You do this by using quotes (so-called double quotes, not
apostrophes aka single quotes).
Secondly, you need to either double your backslashes or use raw strings;
otherwise the \t in \theexe will be treated by Python as a TAB, not as
two characters \ and t, and similarly with \n \r \f etc etc.
So: r'"C:\program files\some directory\engine\theexe.exe"'

Thirdly, there seems to be some perceptual problem here. I don't see how
it could "run fine" if you type the same guff directly at the command
prompt. It's the same program processing your input. Example (Windows
XP, SP 2):
C:\junk>c:\program files\textpad 4\textpad.exe
'c:\program' is not recognized as an internal or external command,
operable program or batch file.
C:\junk>"c:\program files\textpad 4\textpad.exe"
[works OK]

Fourthly, this mailing list is for discussion of Mark Hammond's
python-win32 aka win32all package. news:com.lang.python is more
appropriate and would give you a wider audience.
Cheers,
