mooms I did what you said, made the winrar + Themes an .exe of it and added it to WinToolkit and had a Windows 10 .ISO created.
It now installs perfectly.
Thank you for your support.

mooms maybe I'm not doing it right.
I now have these files.
SFX_WinRAR_x64_6.01-nl.exe
WinRAR_AddOn_x64_6.01-nl.zip (do i need to unzip this folder ?)
And what should I have started in my setupcomplete.cmd?
I have this line in it now,
IF EXIST "%SLocal%\SFX_WinRAR_x64_6.01-nl.exe" "%SLocal%\SFX_WinRAR_x64_6.01-nl.exe"
Should I place the WinRAR_AddOn_x64_6.01-nl.zip along with SFX_WinRAR_x64_6.01-nl.exe in my Windows 10 ISO
I don't even use it anymore, but when you are in the AIO integrator, it's the silent install + SFX tab. You can add any executable (msi, exe) and updates with any switches you want
