It looks like your connection string in AFService.exe.config is incorrect.
Mine looks like this:
<add key="connectString" value="Persist Security Info=False;Integrated Security=SSPI;server=sqlservername;database=PIFD;Application Name=AF Application Server;" />
Can you post yours?
For Class not registered error, I would request you to check version details i.e. PI OLEDB (x86 or x64) and Sql Server native client(x86 or x64). If there is a mismatch in the driver then would request you to configure relevant version to fix the same.
