I tried to get the serial of winzip 8 using the tutorial to get serial no of winzip 7 and i couldnot do any good. help....

The new version proctection scheme may have changed, from slightly to substantially. I have not checked it myself. Try searching for the short pieces of code depicted in the tutorial. It may happen that the coding is the same, but it just got relocated to a different area in the compilation /linking of the new version. OR, the authors of WinZip became tired of giving away their app, as they have been doing, and implemented a more elaborate protection. In that case, the literal use of the tutor will not be of much use, and you may have to explore the new protection. Keep in mind that, as a rule of thumb, programmers tend to change the DETAILS of protections, but the philosophy of it tends to remain constant (Protectionist Personality Trait? or Efficient re-use of Code?).
Hope this helps.

Winzip 8 has the EXACT same protection as ALL of the previous versions. Only the addresses have changed. The same breakpoints etc. all still work.

(ask any of the regulars here....I know my winzip hehe ;-))
