怎么获得Webpack版本的许可证？

我从Xilinx网站下载并安装了ISE Webpack for Linux。
它安装没有问题，我能够使用它的一些功能。
但是，每次启动该程序时，它都会告诉我没有许可证，并告诉我当我单击“确定”时许可管理器将启动。
但是当我点击OK时，没有任何反应。
我还尝试通过执行以下操作启动许可证管理器：帮助 - >获取许可证密钥和帮助 - >管理许可证，但在这两种情况下，一切都没有发生。
当我使用该程序时，我能够进行综合并执行模拟，但是当它尝试实现我的设计（地点和路线等，......）时，会出现一条错误消息，告诉我没有找到许可证文件。
我还能做些什么来让许可证管理器出现/获得Webpack版本的许可证？



以下为原文

I downloaded and installed ISE Webpack for Linux from Xilinx website. It installed without problems, and I am able to use some of its functionalities.

However, every time I launch the program, it tells me there is no license and tells me that the license manager is going to start when I click "OK". But when I click OK, nothing happens.

I also tried launching the license manager by doing: Help -> Obtain a license Key      and     Help -> Manage License,   but in both cases, nothing at all happens.

When I use the program, I am able to do synthesis and perform simulations, but when it tries implementing my design (place&route, etc, ...) an error message appears telling me no license file was found.

What else can I do to get the license manager to appear/ get a license for the Webpack edition ?
