I have updated the SQL Server Express 2005 to 2014. Both the POS and MANAGER both work fine on Server and Client. But now I can not open the Store Administrator on the Server.
The response is 'Runtime Error: Class Not Registered -2147221164 (80040154). Tried uninstalling RMS and reinstalling but get the same problem. The client computer Configuration Test Database is OK, but Connect to Database responds "Failed to connect to database RMSDATA"
