Bootcamp Amd driver updates says "Setup has dectected an incompatible build. setup will not exit."

You can run the brigadier script. I have it in my Downloads folder on the macOS side.

Done.

The WindowsSupport.dmg ( or .zip) is the file you need.

Are Bootcamp drivers installed? If not, Download and install Windows support software on your Mac - Apple Support. In some cases, the BC drivers can install properly, where the drivers from the AMD website may not.

Since you already have Windows installed, you will need to separately download Bootcamp drivers, which requires a USB. If you do not have a USB, then you will need to use Brigadier (https://github.com/timsutton/brigadier).

You will need to re-download it on the macOS side. After you have downloaded it extract the files, install Paragon NTFS trial version (https://www.paragon-software.com/home/ntfs-mac/) and copy the extracted folder/files to Windows, uninstall Paragon NTS, boot into Windows and run the setup.exe.

You can download it in Windows and run it. It will create a .zip file that you can then open and extract and run the setup.exe from the extracted bundle.

You need to download the brigadier.exe file.

You need to run the script. If you post a screen shot of the files and directory where you downloaded Brigadier, I can tell you the exact steps.

Can you download and install 7Zip? I am able to see the files inside the .DMG. See the attached example.

Do you want to take a look at https://cloudconvert.com/dmg-to-zip? You will need an internet connection.

Switch to macOS, and copy the DMG file from the Windows partition to the macOS side and check if you can open it in Finder.

In Disk Utility, click on the Bootcamp partition, unmount it, and then try to mount it read/write under Paragon NTFS. Apple driver and Paragon NTFS conflict with each other.
