I am using Windows 7. After installing Godot from a browser, I get two errors:
OpenGL ES 3.0 Renderer: GeForce GTX 980/PCIe/SSE2 ERROR: EditorSettings::create: Cannot find path for cache directory! At: editor\editor_settings.cpp:756 ERROR: EditorSettings::save: Cannot save EditorSettings config, no valid path At: editor\editor_settings.cpp:934
I am new to game engines, and I don't really understand what these errors mean. I had a similar problem with Unity before I gave up on it.
If it helps any, when I try to open a demo project in Godot, it crashes and suggests I use Visual Studio to debug it. If I do this, the Visual Studio debugger reports this:
Unhandled exception at 0x0000000140003F05 in Godot_v3.0.2-stable_win64.exe: 0xC0000005: Access violation reading location 0x0000000000000000.
