patran无法导出inp文件？

patran导出inp文件时报错：$#     The PCL library file, abaqus.plb, associated with the current analysis preference, ABAQUS, does not exist.  This file is required and used to store analysis code specific PCL functions. This could be an installation issue. You must select a valid preference from the Preferences menu before you can continue.请问怎么解决啊
