Try an alternate calling method and see if it makes a diff :
my $function = Win32::API->new('test.dll', 'i', 'i') or die "import: $!
($^E);
my $return = $function->Call(0);
or
my $startSimulation = Win32::API->Import('test.dll',
'int startSimulation (int eRunMode)') or
die "import startSimulation: $! ($^E)";
my $return = startSimulation (0);
print "$return\n";
