Archicad 28 LiveSync installation problem

Hello everyone.
I am having a problem installing LiveSync for Archicad 28. I downloaded the latest version (1.2.0.0002) of LiveSync. However, during installation, Archicad 28 is not available for selection. Only Archicad 27 is available! What could be the reason for this?
Best regards,
Jan

Hi, is the installation method of AC29 on your device the same as AC28
(for example, it is directly unzipped instead of installed step by step, which will affect the normal writing of the registry).
