I'm not able to open the sln file with VS 2017 and VS 2015, with the following error.

May I know the version of your Visual Studio, please?
Dear Jing X.,
Could you please let me know how it is going?
I'm still in the same trouble. I suspect the input matrices, because those turn out to be not exactly hermitian, but having slight numerical noise giving unsymmetry. I'm not sure that this triggers runtime error in feast, but I couldn't find any other issue in my input.
If it is possible to look inside the feast subroutine, but it must be not allowed to me.
I have resolved the problem. As I guessed above, it was due to my input, which turns out to be not exactly hermitian.
I was using the full matrix input (parameter uplo = 'F') to the zfeast_hcsrgv, but that was mistake because my input matrix was not exactly hermitian.
To avoid this trouble, I extract upper triangular part, and then use the option uplo='U'. This works very well.
I found that a slight deviation from the hermitian property in the input due to some numerical noise can trigger a runtime error (access violation) of the zfeast_hcsrgv routine.
Thanks a lot.
