Bungie failed to download configuration files
It also doesn't automatically copy the contents of its .log files to another file, such as to a .lo_ file. If you want to control the maximum size of log files, implement a process to manage the log files independent from the Configuration Manager client for Linux and UNIX. Then the old hard drive failed, and after replacing it and reinstalling GOG Galaxy to the same location (D:\GOG Galaxy) I now get the Installation failed: Configuration Error" on every install again. I've tried the Verify/Repair trick some have suggested in other threads, as well as running the client as an administrator, but that didn't help.
