WIN7系统，之前有装aspen,中望CAD等软件，系统装有加密软件（亿赛通），安装时按照以下步骤安装的：

1. Intall ANSYS 18.0, specify name of the host which runs/will run license server when asked.

2. Intall ANSYS 18.0 License Manager, do not install license file.

3. Replace files in "Program Files\ANSYS Inc\Shared Files\Licensing\winx64\" with cracked file in crack folder

4. Generate your license file using A180_Calc_DownLoadLy.iR.exe

5. Setup/start ANSYS license server using license file generated.

In case of troubles click&read "Getting Started - Licensing" and "Getting Started - Installation"

Use firewalls to block ANSYS from calling home.
