MAGNET Explorer might give the following error: Could not save NVidia application settings (-1).
This error typically starts to appear when NVidia program settings (profile) cannot be saved.
Typically this occurs because of corrupted display driver database.
Use following steps to fix this:
Go to folder C:\ProgramData\NVIDIA Corporation
And rename “Drs” folder to something else. (For example to “Drs_(backup)”) Create new empty folder “Drs”.
Start MAGNET Explorer – error should not appear anymore.
This operation however resets all other applications 3D applications settings as well – for example if you have Autocad – Autocad might switch to use different graphic video card (depending on what kind of video cards your machine is using).
You might need to switch to desktop, right click – “NVidia control panel” – “3D settings” – “Manage 3D settings” – “Program settings” - Select Autocad, select High performance NVIDIA processor. (If Autocad does not restore this by default).
