例如，包在一个产品演示版外的数字包装器可以警告用户，软件再用几次就要关闭了。

For example, a digital wrapper around a demo version of a product could warn the user that there are only a few more USES of the software left before it shuts off.

再者如你的P5.0 是演示版或曾安装演示版，那个授权档可能与软件不配合。

Also is your P5.0 is demo version or you have installed demo version before, incorrect license file have same error also.
