Installation of DirectX (for 6.)
If the installation of DirectX fails, the GP Manager cannot start as it requires functions that are provided by Direct 2D and Direct 3D. Error messages such as "GP_DV_FussDruck.DLL cannot be loaded" appear.
Troubleshooting
DirectX often cannot be installed if the driver for the graphics card has not been installed correctly. Make sure that you have installed an up-to-date graphics card driver from the graphics card manufacturer.
Then install DirectX manually. You can download a version of DirectX in the .\GpTools\DirectX Find folder. If the computer has Internet access, you should find the file dxwebsetup.exe start. Alternatively, you can also use the directx_Jun2010_redist.exe execute. If you do not have DirectX, you can download the latest version from the https://support.microsoft.com/de-de/kb/179113 download.
When you open the file directx_Jun2010_redist.exe and the error continues to occur, then you must dxwebsetup.exe execute.
