I could not launch destop client of tryton 5.2

Hi everyone here:
Am using tryton 5.2,i was about trying to execute the client desktop , but there was an error shown :

`KDEInit could not launch 'tryton':`
    Could not open library 'libkdeinit5_tryton'.
    Cannot load library libkdeinit5_tryton: (libkdeinit5_tryton: cannot open shared object file: No such file or directory)

thanks in advance

Could you provide us the Operating System you are running and how you installed the client?
