ok bro with patch 1.03 it works on Win7 x64

.
unfortunately the size gets a lot of bigger.
so i changed step 8 to this:
8: Go to
install directory/data,run FreeArc,compress the following files
Code:
ep999-000.rmdp file
Output archive: Data5.cab
Compression: -m9x -ld192m -s256m
Make exe: Not checked
then it fits.
