Custom Executable file name with spaces handled incorrectly

Example run configuration:
The folder C:\Program Files\MAXON\CINEMA 4D R14
contains two executable files and one Linux executable without an extension:
CINEMA 4D.exe
CINEMA 4D 64 Bit.exe
CINEMA 4D 64 Bit

Settings the command to
C:\Program Files\MAXON\CINEMA 4D R14\CINEMA 4D 64 Bit.exe
will run CINEMA 4D.exe instead. The same happens if
CINEMA 4D 64 Bit.exe
is removed/renamed.

Removing
CINEMA 4D.exe
fixes the issue (i.e. CINEMA 4D 64 Bit.exe is executed).

Renaming
CINEMA 4D 64 Bit.exe
to
CINEMA_4D_64_Bit.exe
and adjusting the command path accordingly also fixes the issue.
