Launcher GUI doesn't work on Windows 7 installer (WontFix)

The UI based launcher doesn't work on windows 7. You can still install using the text-mode installer, however.

I'm just recording that the reason for this is:
- On Windows 7, the "job object" registration fails
- the "job object" was introduced to make sure that when you close the installer UI, the aria2c process is killed (so that it doesn't keep downloading in the background). This is only necessary when using the UI, as when using console/text mode installer, closing the console window will terminate aria2c automatically
- Therefore, even if the UI works, if the job object registration fails, we use the console/text mode installer, to make sure aria2c is killed if you close the installer (well, close the terminal). If we allowed the UI, we'd also be allowing the aria2c process to run in the background if you closed the UI window.

TODO:

- [ ] Note this in the wiki
- [ ] Add option to text mode installer to run from temp folder? This option is not given in the text mode installer.

该 issue 描述了 GUI 启动器在作业对象注册时出现的 Windows 7 特定故障，这会导致强制回退到文本模式安装程序。首先检查安装程序中处理 Windows 进程管理和作业对象的代码。查找 aria2c 进程的生成和作业对象注册逻辑。确定是否存在针对 Windows 7 的变通方案，或者回退行为是否是预期的解决方案。需要在 Windows 7 环境或模拟环境中进行测试以验证任何更改。
