I'm assuming this is retyped and you missed the '.msi' in retyping?
If not, that may be your issue.  Also, 'set' doesn't require quotes
around a value with spaces, and you're also quoting %PYTHONDIR% when
you use it in the msiexec command, so you're actually double-quoting
the dir name (which could also be the issue).  And, not necessarily an
issue that would prevent installing, but you may want to make sure
you're in the correctly-bitted Program Files directory if you're on
64-bit Windows (%PROGRAMFILES% for 64-bit, %PROGRAMFILES(x86)% for
32-bit; %PROGRAMFILES(x86)% will not be defined on 32-bit Windows or
in a 32-bit process on 64-bit Windows).
