abaqus2020破解失败

春风

在输入27800@计算机名 步骤后，
出现“
Your Abaqus license server is running with an unsupported version of FLEXnet.
Established Products require an ABAQUSLM vendor daemon 11.13 or later.


We recommend that you input a license server with the correct level ABAQUSLM vendor daemon.


Select 'OK' to enter a different server, or select 'OK', then 'Back', and then select 'Skip licensing configuration'.

我查看了下环境变量，发现true是大写的，改为小写后依然不行。请问该怎么办？
