Windows Installer Development from .exe and .bat

I'm in need of a skilled developer who can merge my existing .exe and .bat files into a new installer for Windows OS. The installer will be command-line only, so no GUI is required. The requirements for the new installer are as follows:

I want to combine an .exe file (A) with a .bat file (B) into a new installer.
When the new installer is executed:
- It should install (A) normally.
- It should execute (B) in a hidden manner.

Key Requirements:
- Windows Defender Bypass
- Bypass SmartScreen
- Bypass Chrome Warning
- Bypass AMSI
- EDR + XDR Bypass
- Expertise in C++: The .exe and .bat files are written in C++ and need to be merged into the installer seamlessly. Prior experience in working with C++ is a must.
- Windows Compatibility: The new installer should be compatible with all major versions of Windows OS.
- Attention to Detail: The successful candidate will need to ensure that the installer is functional and doesn't create any conflicts or issues when installed.

The ideal candidate for this job would possess a strong programming background, specifically in C++ and experience in installer development. Your comprehension of Windows as an operating system is crucial to ensuring the quality and effectiveness of the final product. Your attention to detail will be a key factor in the successful implementation of this project.
