Hi, thanks for your fast replies and sry for my delay.
>>Where does WIM_GENERIC_WRITE.. come from?
They are defined in the wimgapi doc, you can find them with waik.

@ikegami I did try a simple open ... I added your encode line but it still doesnt work. 
use Encode qw( encode );
my $filehandler = encode('UCS-2le', 'C:\\data.wim');

my $wimfile = new Win32::API("wimgapi", "WIMCreateFile", ['S','C','C',
+'C','C','C'], 'N');
my $value = $wimfile->Call($filehandler,WIM_GENERIC_WRITE,WIM_OPEN_EXI
+STING,WIM_FLAG_VERIFY,WIM_COMPRESS_NONE,WIM_OPENED_EXISTING);
