"Could not load file to assembly 'NPOS.LicenseService Version 1.0.0.0, Culture=neutral, PublicKeyTocken=null, or one of its dependencies. The system cannot find the file specified" - Error message is shown while user is trying to login into Ginesys POS Application.

CAUSE

A probable reason for the error is the local antivirus in the POS Server, especially Windows Defender or Microsoft Security Essential has removed or quarantined a Ginesys POS Application file (NPOS.LicenseService.exe). This behavior is detected where the Microsoft Threat Definition has recently got updated.

You can ensure the above as the cause if you find the above mentioned Ginesys POS Application file in quarantined list in antivirus history. 

RESOLUTION

You are requested to executed the following steps:

  1. Add POS locations to Antivirus Exclusion List.

  2. The POS folders also have to be added to the Antivirus Exclusion List 
    The POS folders are located in: <Ginesys POS installation drive>:\ProgramData\GINESYS>
