You might try leaving off the double-quotes in $proggie and using the PROGRAM LIST version of system, since it cuts out the shell and executes the program directly (which, I believe, is what is causing your problem).

So your code would become (roughly):

my $proggie = 'C:\Program Files\Microsoft eMbedded Tools\Common\EVC\Bi
+n\EVC.EXE';
my @switches = ('/MAKE', 'Project - Win32 Debug');
system($proggie, @switches);

Note that this is untested. Hope it helps.
