Followed istruction but line code not found

[pinkfloyd11]

Hi
my dll version end with 6062.0

With IDA I have search "lic_call_1812CE870" but nothing has been found. Why??

[sl4v3k]

because "lic_call_" is name i added locally to mark the function, You are not going to have it in Your IDA decompilation

[pinkfloyd11]

And what I should search?

[sl4v3k]

send me dll i will find right place or You can find by searching surrounded bytes as signature

But how you understand which line of code must be changed??
And still more incredible how understand which will be the new line code??

In Your case, the function is here, 0000000181B49289 in IDA view:

But how you understand which line of code must be changed??
And still more incredible how understand which will be the new line code??

just debug the app and first check functionality and see memory it uses
