CUDA Visual Studio 2017 Integration Corrupted After Attemp to Update Nvidia Nsight

I have CUDA 9 development kit, and I have tried to update Nvidia Nsight unfortunately the installation failed so I have tried to uninstall the existing Nsight Installation to install the new version. The uninstallation finished with no error message but seems It hasn’t removed the extension completely corrupting CUDA Visual Studio 2017 Integration. Now CUDA setup and Nsight setup alone both fails every time.

The installer is missing any option to clean install related components and removing the whole Visual Studio or resetting all extensions It’s an huge waste of time. What are the files and register keys installet so that at least we can try a manual remotion of corrupted programs?
