Inno Setup deployment of CUDA program in Windows 10

I’m a programmer of large finished open source program using CUDA that I want to deploy to Windows 10 end users. Inno Setup is a great open source tool for such things. I would like NVIDIA to provide a cudaInstaller.exe that checks GPU device, driver, and installs only the cuda runtime (cudart) on the users machine without having to install the huge GPU Computing Toolkit for the end user. I will install cudaBlas, cudaSparse, and other libraries the user needs with Inno Setup. It would be nice if that program returned useful error codes such as '0-success, 1-incompatible device, etc.

Thanks,
