I am using Abaqus 2020, visual studio 2019 and parallel studio XE 2020 to run fortran subroutines. (visual studio and parallel studio are trial versions). The installation sequence, option selections and environment properties changes are made as per the attached guideline available in public domain. However when the verify command is run, it is throwing a linking error. Is there anything additional to the attached procedure which has to be followed?. Is the issue because I am using trial version of visual studio and parallel studio?. Thanks in advance for your valuable suggestions.
