Error on opening the Retail POS machine in ax2012

I have successfully created Store database and channel database, and executed the xxxx jobs.

The synchronized data can be found in store database. Everything is good so far.

But when I was launching the POS client, I got the errors 1.“The application could not be initialized” and 2.“A system error has occurred. The application will close”.

I tried the link also  Error when opening POS ,  POS Error  and  Retail POS: "The application could not be initialized" launch error.  

Any help? to overcome this error! please!

Thanks & Regards,
