Hi!

I need to crack a software. I have a 45 day trial of this software but with the function "save" "save as" and "export" locked.

I read tutorial and guide on the web but i don't understand what i must make... (informatic isn't my work )

Can you help me?

....i make excuse for my english....

I think you should crack the time limit first, before moving onto disabled functions.

Also, it might prove futile if the code to perform save, save as, and export are not even present in the file.

Hint 1: Learn to crawl before you walk. If you've got no idea what to do about this, you probably won't succeed in 45 days anyway. Seems like you're quite the newbie, so consider learning a bit more about cracking before you "need" to crack something.

Hint 2: Like LLXX said, go for the 45 days time limit. First think of the ways in which the program could know how long it's been running. There are a few ways of doing this: either storing info in the registry or on disk (which could be on file or directly written to disk, the latter being more unusual though).

Hint 3: Check the binary of the file. Is it packed or straight? Does the binary give you valuable hints to this or that? Look for strings, if the programmer is a stupid idiot those will give everything away - and a lot of programmers are still stupid.

Hint 4: Consider that by coming here and asking a question like you did might annoy people here and raise the admin flag on you. However helpful people might be, you're wearing their patience down with a general "teach me to crack"- request.

...excuse me if i have annoy any people...but i founded only this forum on this argument and i has thinked, maybe mistaking, that you could help me...

So...i have understand that this forum is only for computer scientist...

thank's however

heya,

i don't think you annoy anybody. the overall hint is probably that gaining enough reversing / cracking skills you are looking for - is not a very quick way.
the forum here is to help you going this way, and to provide help when you are stuck.
this includes you need to learn quite a few things until you could for example use a disassembler and debugger, and understand what you read there. since these topics are described very well on the net allready, its a good idea to start the research on the net, looking for windows assembly ressources, low level debugging, tools like IDA and ollydbg etc ... also explore the links you find on this forum.
if you dont find your way into all that - please ask and write where exactly you are stuck, what you were trying to do, what does not work ... and such, you will get much more satisfying replies then, I am sure

i see... but i'm not a english native speaker and explain my problem is difficult for me. I hope to speak frankly....

so...

in the last 2 day I am successful to eliminate the "watermarks" and the 45 day limit (i have used a hex editor).

My only problem now, is understand if in the demo software is present the function save and export, and therefore unlock these...

i have understand that this process isn't simply and quick but i'm happy if you can link me to manual or guide or anything for to learn the necessary step.

thank's
