About an UDF function use in Ansys fluent 19.0 R3 and Visual studio 2017

When I opened my fluent from below link

C:\Program Files\ANSYS Inc\ANSYS Student\v195\fluent\ntbin\win64\fluent

And when I read the Case file, I could not see the my file.

Additionally, I am facing a error which I showed in screen shot.

Can anyone help me to figure it out?

    I'm not familiar with UDF setup, so I will wait for others to comment on that part.

    However, I see you set working directory to be under C:\Program Files\ANSYS Inc, this is not good because you will be writing files on there and will likely get into permissions issue.
