Programs don't start

In this case there are two possible errors:

1. Windows considers downloaded files as dangerous:

Click the exe file (e.g. DCBaug.exe) with the right mouse button and select "Properties" in the menu. At the bottom under "Hidden" there might be a text: "This file came from another computer and might be blocked to help protect this computer". In this case, activate "Unblock".

2. The driver of the graphics card should be updated. There were problems with different NVIDIA cards and with AMD FirePro W 5000:

Start Device Manager under Control Panel. Open "Display adapters", click your display adapter with the right mouse button and select "Properties". On the page "Driver" select "Update driver". After finishing, restart the computer.
