Fretlight Studio 6 Windows PC version update existing C++ code

I'm seeking an experienced software developer with a strong background in both Windows and macOS to update the existing C++ code to resolve dependency issues. And produce a install program that will run reliability on all Windows version including Windows 11.

The software currently supports both Windows and macOS, however, a future project will address the issues with the MAC version of the software. Thus, the hired professional must have capabilities in working with multiple operating systems. A knowledge of C/C++ is required

Here what's needed:
- Diagnose the issue on the Windows version of the software.
- Repair the two functional bugs or broken dependencies causing disruption within the software.
- Quality assurance test to ensure issues are addressed effectively.

Ideal candidate should have a solid grasp of troubleshooting, and debugging software applications. They require a strong ability to identify, extract and fix functional bugs. A background in music software could be advantageous, but is by no means essential.
