包括最新版4.5.2都能破解，亲测可用！附带破解方法！

Install Unity and Run. When at the license window just close it.

Copy the patcher to the installation directory of Unity (eg. C:Program FilesUnityEditor)

Run the pathcer (as Administrator). 

Click "Patch". After patching confirmation click "Cre Lic". This will create the file "Unity_v4.x.ulf" in the same directory. (Confirm overwrite if you get the message)

Copy the above .ulf file to c:ProgramDataUnity

Done!

怎么破解：

将软件复制到安装目录如：C:Program FilesUnityEditor；

运行pacher（右键管理员身份运行）；

如果pach报错不用管它，关闭后运行Cre Lic。若是否重写Unity_v4.x.ulf，点击是。

复制Unity_v4.x.ulf到c:ProgramDataUnity中。完毕！（如果找不到文件夹，更改显示隐藏的文件夹即能看到，后者复制前面的c:ProgramDataUnity路径。）
