Trial on Setup

Recommended Posts

Magictor

Hello, 
I come to you for a help
Here I have downloaded for me personally the software EaseUS Todo Backup 12 0 in the installation file 
there's the word Trial. it's weird. I know, but I want to take it off.
Setup:
http://down.easeus.com/product/tb_enterprise_trial
So I decompiled the setup with InnoExtractor
attached zip file setup decompiled
https://www64.zippyshare.com/v/yXFvLPCb/file.html
when I want to recompile the file I get this error

oyyy.jpg

I don't know much about script. 
someone can help me recompile it. 
Thanking you
Good day, everyone.

@Magictor You can't just decompile an executable and expect to be able to "re-compile" it.
You don't have all the libraries/compiler options or even the original environment.

Also, removing the word "Demo" won't achieve anything. It'll still expire.

I'd study up on assembly language and how to use a debugger if I was you.

Best debugger?

I like this one:

Thank you so much Pequi for your answer 

You're gonna think I'm a loser, but how do I find the word Trial with x32dbg?  

I search but I not find

@Magictor asked

"how do I find the word Trial with x32dbg?"

That would be complicated. You'd have to learn how to set it up first, and then go on to searching for strings.
A debugger is useless without learning assemby language first.

I have no idea if EaseUS encrypts the executables. If it doesn't, you can use HxD, a simple hex-editor.

https://mh-nexus.de/en/downloads.php?product=HxD20

CRTL-F and seach for "Demo" in both modes (editor encoding and Unicode). You would have to change DEMO to something with 4 digits, like "TRIAL" or "REAL". Simply deleting "DEMO" will mess up all the calls within the executable and it will crash.

But as I said, that will NOT make it a non-DEMO. I'm at a loss on what you are trying to achieve.

PS To thank a reply, click on the blue heart. Don't say "thank you". Forum rules.

I tried already with Hex Editor Neo but I find no word Trial must be compressed but in what format?

I try ExeInfo but it is not what is with compress

I know it's weird but it's personal as you say it does nothing will change in the application, but I'd like to remove this has got to be feasible?

Thank you

i think the dev encrypted the pgrase to prevent reverse engineering..

Yet I manage to remove the word Trial in the script with innoextractor but then I can't recompile it

Changing a file in anyway (ex. removing the word Trial) changes it's hash (md5) and that makes it fail security check which might be enforced at compile time.  That is how many antivirus programs flag out files with legit name, author, version, etc. but mismatching hash (cracked files).  Therefore, check to see if any hash security check is enforced at compile time, most likely based on some script in the original setup.

He did not decompile exe program but setup, someone may  decompile inno setup then compile it making new installer

Try changing MinVersion value

Read inno doc

Thanks to both of you, but I've already changed the value of MinVersion. it works, but then I have another mistake.
