Yeah, doesn't work for me since there is no folder of that name on my system.

This is yet another issue with the GOG Galaxy app, that just never gets fixed.

如果您无法启动GOG GALAXY，并且Galaxy确实未在后台运行，请尝试以下解决方法：

删除下面的文件：
C:\ProgramData\GOG.com\Galaxy\lock-files\GalaxyClient.exe.lock

您可以使用“运行窗口"（WinKey + R组合键）并输入以下内容来访问目录：
%programdata%\GOG.com\Galaxy\lock-files\

重启客户端。
