find out how the checksum is calculated and update it to the correct checksum? or perhaps find out where the checksum is compared and remove the comparison?

ok thx .. problem checksum is compared in software .. and software is packed with Xprotector and i can not unpack him for passed the comparaison

Well, in that case, unless you can unpack the file, it looks like your screwed !
