Error

Error #0149: Client version (XX) incompatible with server version (YY). Please, update MyChat Client through GPO

 

Error description

You can't connect to updated MyChat Server with your MyChat Client version. Application versions must match.

 

Problem solution

Update MyChat Client via domain Group Policy (GPO), or by installing the MSI package manually. You need elevated privileges (Administration rights) because MSI package installs the application to the folder Program Files.
