Cuda 9.0 patch 1 installation problem

Graphics card: Geforce GTX 1080
OS: Windows 10

I am trying installing Cuda 9.0.
Cuda 9.0 installation was successful, but patch 1 installation is failed.
There is a symptom that the installation screen appears and disappears for just a moment while installing Patch 1.

I have searched the symptom and have found the forum below.

However, I don’t think it is a good solution.
Does anyone know other solution?

Can you try Deleting C:\Program Files\NVIDIA Corporation\Installer2 and then try to install once again.

Thank you for your reply.

After deleting the folder, I have been able to install patch 1 successfully.
And other patches (2, 3, 4) also have been installed correctly.
Thank you again for your help!

Thank you!!
