Look for the SambaSettings.txt
file in one or both of the following locations:
NOTE:
ProgramData
is a hidden folder
C:\ProgramData\SambaPOS\SambaPOS5\
C:\Users\USERNAME\AppData\Roaming\SambaPOS\SambaPOS5\
Open the file and edit the Connection String…
<ConnectionString>Data Source=localhost\SQLEXPRESS; User Id=sa; Password=sambapos; Database=SambaPOS5;</ConnectionString>
If the Connection string is not set, it will look like this (self-terminating):
<ConnectionString />
To set it properly, make it look like this:
<ConnectionString>CONNECTIONSTRINGDETAILS</ConnectionString>
