binary patch of the compiled installer
 

Hi,

I have used NSIS to compile my installers for a while. I have come to the point where I want my affiliates to be able to add an id number to my compiled installers.
This ID would be extracted anbd used during the installation.
I cannot recompile the installer with NSIS for every affiliate, instead I must give my affiliates an install.exe for them to, somehow, add their Id.

My idea is to write an app that perform a binary patch of the install.exe. This patch would replace a string with another, affiliate unique, string.
This is problematic due to the CRC check that I cannot disable, due to security reasons.

Anyone with experiece from situations like this?
Any suggestions?

cheers

You can append data to the installer, it won't be CRC'ed.
