我已经尝试了该站点上的所有内容，但似乎无法正确启动 SQL Developer。我使用的是 Oracle express 版本和 windows 7。我的 SQL Developer 版本是 4.1.3，JDK 版本是 jdk1.8.0_101。
It gets stuck on here and doesn't start:
它卡在这里并且无法启动：
I tried moving SQL Developer to different folders. I tried installing different versions. I tried everything on this site but nothing solves my problem or when something works it is temporary and next time I open it, it is stuck again.
我尝试将 SQL Developer 移动到不同的文件夹。我尝试安装不同的版本。我在这个网站上尝试了所有方法，但没有解决我的问题，或者当某些东西起作用时它是暂时的，下次我打开它时，它又卡住了。
Please help, and moderators please don't close my question because nothing on here works for me!
请帮忙，版主请不要关闭我的问题，因为这里没有任何内容适合我！

Go to your AppData folder under your Windows OS User's home directory.
转到 Windows 操作系统用户主目录下的 AppData 文件夹。
Under there is a roaming profiles directory, and under that there should be a SQL Developer folder.
下面有一个漫游配置文件目录，在该目录下应该有一个 SQL Developer 文件夹。
In THERE, you'll see a system4.1.3.x... folder - nuke that.
在那里，你会看到一个 system4.1.3.x... 文件夹 - 取消它。
Try starting SQL Developer again.
再次尝试启动 SQL Developer。

Now restart the SQL Developer. It will ask if you would like to import existing profile? Select 'No' and click Next.
