ever since version 1.2g i haven't been able to compile with PackEXEHeader in my script file. i'm using upx with the following line -
PackEXEHeader "temp.dat" "..\upx\upx -9 temp.dat"
the last thing it says in the console window is -
File size Ratio Format Name
-------------------- ------ ----------- -----------
34816 -> 20992 60.29% win32/pe temp.dat
Packed 1 file.
