I'm afraid I don't have access to a Windows 7 machine to test on, just Windows 10, and I don't really know enough about Windows to make any guesses.
Best option is to look for the log files in `AppData\Roaming\Godot\app_userdata\Prog\logs` -- they should look something like:
Godot Engine v3.3.2.stable.official - https://godotengine.org Godot Engine v3.3.2.stable.official - https://godotengine.org Godot Engine v3.3.2.stable.official - https://godotengine.org OpenGL ES 3.0 Renderer: Radeon RX 580 Series (POLARIS10, DRM 3.35.0, 5.4.0-90-generic, LLVM 12.0.0) OpenGL ES Batching: ON **WARNING**: ObjectDB instances leaked at exit (run with --verbose for details). At: core/object.cpp:2132:cleanup() - ObjectDB instances leaked at exit (run with --verbose for details). **ERROR**: Resources still in use at exit (run with --verbose for details). At: core/resource.cpp:450:clear() - Resources still in use at exit (run with --verbose for details).
If there's anything else in there, it might give me a clue as to the problem.
