As the title says, this batch script installs the XignCode Bypasser.

Xigncode is a software bundled with games to analise running programs and prevent cheating. (Sometimes, it prevents the game to load at all on the newest Windows releases.)

For this, a bypasser was created that disables this check, allowing players to run the game (if they couldn't), mod the game (One Click Tool, for example) and (if you want) cheat.

Copying the files manually is a boring task that can lead to mistakes (copying from the wrong location, deleting the Bypasser by mistake, ....).

For that, I've made the following batch script that does all the copying and extraction:

This script has many functionalities:

• Automatically fetches the game installation path from the registry


• Automatically detects the Windows "bitness" (to decide if it patches the 64-bit folder or not)


• Allows to change the game installation path for the running script


• Extracts the files and automatically assumes the path where they were extracted to


• Verifies if it was already installed, allowing to skip or install anyway

Knowing it is a rather large script, I've tried to split it into multiple functions, to make it easier to understand, read and maintain in the future.

You can see the complete instruction list on https://github.com/ismael-miguel/xcb-installer

As far as I know and tested, this is working as it should. All it's functionalities function as intended and there seem to be no obvious errors.

Regarding readability, error handling and readability, is there anything else I can improve?

Disclaimer:

Seeing that this action of bypassing XignCode may be against the Terms and Conditions of the game, I've asked about it on Are we allowed to post questions that allow you to do something that may be against the Terms and Conditions of another software? (to which 13 upvoted the only answer, 1 downvoted).

This script does not allow you to get the files in any way, shape or form: it only does all the extracting and copying. If you want the files, you have to get them by yourself. I do not want to make it any easier to get the needed files.

Batch is a language I'm not familiar with, requiring me to learn a lot from all the websites and links available in comments.
