objCompany = new SAPBOBSCom.Company failing in Windows Server

We developed add-on for SAP Business One 8.8 PL 13 and solution working as expected. After complete testing when we try to install and run in Client Production Environment, we encouter issue. The only difference between my development environement and Production Environment is SAP Business One 8.8 PL 14.

We get System.Exception with now message on following line

objCompany = new SAPBOBSCom.Company.

Also found, SAP Business One Fixed Assets add-on not working as expected.

Thanks in advance for your help / error solving clues.
