Unable to compile cuda file with MATLAB 2017a, VS2017 and cuda 9

I'm trying to compile one .cu file with MATLAB 2017a, cuda version 9 and Visual studio 2017. It is showing

   >>mexcuda -v moveVariableToCUDA.cu

It looks as if you might perhaps have to reinstall VS2017; see https://developercommunity.visualstudio.com/content/problem/38434/devenvexe-missing-after-cancelling-update.html

But mex -setup is giving me following output. I'm using VS2017 for mexopencv and matconvnet. It's 3rd time when i have uninstalled and reinstalled VS2017.

MEX configured to use 'Microsoft Visual C++ 2017 (C)' for C language compilation.
Warning: The MATLAB C and Fortran API has changed to support MATLAB
   variables with more than 2^32-1 elements. You will be required
   to update your code to utilize the new API.
   You can find more information about this at:
   http://www.mathworks.com/help/matlab/matlab_external/upgrading-mex-files-to-use-64-bit-api.html.

To choose a different C compiler, select one from the following:
MinGW64 Compiler (C)  mex -setup:'C:\Program Files\MATLAB\R2017a\bin\win64\mexopts\mingw64.xml' C
Microsoft Visual C++ 2017 (C)  mex -setup:C:\Users\ipcv16\AppData\Roaming\MathWorks\MATLAB\R2017a\mex_C_win64.xml C

To choose a different language, select one from the following:
 mex -setup C++ 
 mex -setup FORTRAN

Could you check under C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7 to see if there is a devenv.exe somewhere there? It appears to be a key front-end for compiling for VS.

Hmmm it might not be connected but I had the problem that Matlab insists on a specific CUDA toolkit. 2017b, as far as I know, starts to support CUDA 8, 2017a doesn´t. Anyway, in my case adapting the config file nvcc_msvcpp (in the log it looks for it under "C:\Program Files\MATLAB\R2017a\toolbox\distcomp\gpu\extern\src\mex\win64\nvcc_msvcpp2015.xml'...FAILED") worked: copy it to a local folder, and look which compiler and CUDA version it requires. Replace by what you have and hope for the best. Compile with -f nvcc_msvcpp201x_custom.xml.
