How can I license the ReSy library in a AXC F 2152 controller?

I am trying to Install ReSy Library on my computer and license it on my PLC as well but I do not know exactly the right way of doing it.

Hello, I guess you downloaded this library from the PLCnext Store? Did you buy a license in the PLCnext Store? The user manual describes the function blocks ReSy10x_10xObjManagerV01, and the parameter IN_LS_LicenseCode :

The alternative license code can be entered here if the license flash card is not to be used.
RESY-DATA-A LIC - 2876847

If the instructions in the user manual do not help, please try contacting the developers using the “Contact” button on the app page in the PLCnext Store.
