Hello,
I have attached the image of the window which popped up during install. If I can add the publisher name in trusted list I think that window will not come. Is that possible?
In order to achieve this you should try to digitally sign your driver package. Please take a look on
"Using Authenticode to Digitally Sign Driver Packages" and
"Driver Signing" articles which should be useful for you.
Also during uninstall, the installer is always uninstalling the drivers which are installed by the installer. Is it possible to not uninstall the drivers during uninstall
I'm afraid this is the normal behavior. Please keep in mind that our Driver framework is designed for installing Software First Install drivers only (which normally should be used by the application installed within your installation package). So, when the installation package will be uninstalled, the driver package will be uninstalled too.
All the best,
Daniel
