The software you are installing has not passed Windows Logo testing
During the installation of RadarOpus on Windows XP you might get 6 times the following error message:
The software you are installing has not passed Windows Logo testing to verify its compatibility with Windows XP.
By default you will be advised to click on STOP Installation. We advise you to click on "Continue Anyway".
This message occurs during the installation of Virtualbox which is needed for the databases of RadarOpus.
If you want to deactivate the Windows Logo testing generally, click on Start, then right click on "My Computer", Properties, then on the Hardware tab, Driver Signing and activate the option "Ignore - Install the software anyway and don't ask for my approval".
