(SOLVED)cudart64_90.dll not installed when installing CUDA 9.0

I have CUDA 9.2. When i imported tensorflow it said no cudart64_90.dll.
So does tensorflow is not available for cuda 9.2?

If you have only 2 files in the bin folder, you should first download base installer before install any updates

you solve the porblem

I have solved the problem.Do you need my help?
