user-defined models in plaxis

Hello Everyone! Currently I'm trying to figure out how does work example programs from this topic:
https://communities.bentley.com/products/geotech-analysis/w/wiki/45468/creating-user-defined-soil-models

After several tries I've downloaded and started ifort compilator in a command line.
But instead of dynamic library i got an error message, like this:

LINK : fatal error LNK1181: unable to open input file "dfusrlib.lib"


As I understand it means this library (dfusrlib.lib) is a part of a original fortran program which was not included in the archive of example (added under the topic above)

So, the question is:
1. Does anyone have this file, or I did understand something wrong?
2. Is there those, who tried to make a user-defined model? I need some specific discussion about non-linear behavior, stiffness matrix, etc.
