Many years late

for those of you who were fed lies by securom

yes there is a way to remove the crap securom burns into your computer upon install

and yes theres a unlock key which is needed.

as you can see from the screenshot typical if else statement

that verifies and checks key's validity against string length via user input.
enjoy.

btw you have to go in memory if your planning on generating a legitimate unlock key

As they say, if man can make it then man can break it

Guy named Pedro put this simple source out awhile ago, maybe this will help people get a foot in the right direction. It's dated so I shouldn't get into too much trouble for posting this
Just make sure the copy or ISO ALWAYS has the SAME Volume Name.
Securom 7,etc+, code available.
I can explain this if anyone needs me to

sorry, I was a tool and needed to clean my code up

 

[SorenAlke]

thanks my friend !

Not even using Ida pro HxD sucks

 

[SorenAlke]

i use ida pro but i also use olly, win32dasm and hiew for patching
