Befor you can use the EFB you needt to download the MIcrosoft .net Desktop Runtime 6 for x86 or x64 for your Windows
Install the .net 6 Runtime.

After first start of EFB.EXE klick setting and set the right path for the folders.

In the EFB folder there is a folder "EFBDaten" which can be in any location. Inside are sample files for the first start of the EFB.
It would be good to save the folder in such a way that you can save the Simbrief flight plan as well as the Topcat files directly in it.

The EFB can also be used on Windows tablets. It is also possible to adjust the height and width of the tabs.

Furthermore, the font size for the Topcat files can be adjusted so that they are easy to read.
Attention, the data from TopCat must be saved as .txt!

Both can be achieved via the “Settings” menu item.

A notice!

If there is only one loadsheet, take-off, landing and weather file, these are automatically loaded into the EFB.
If several files exist, a dialog for selecting the corresponding files will automatically open.
The same applies to the flight plan.
