  Hello,
  I assume the above error appears because of my UDF. However, I have put my case and data files in the directory in which is allowed by my institution to compile codes.
  This is the message I get in the beginning when I open my case file. Is not the UDF properly compiled? What could be the root of the error?
  Will now auto-compile UDF library "libudf".

  Hi,
  The messages indicate that the compilation process is attempting to use the compiler but is unable to find the Visual Studio compiler, which is typically required for compiling C/C++ code on Windows platforms.
  Ensure that you have Visual Studio installed on your system.
