eWayTimer cannot launch. If you try, this notice will appear: "The eWayTimer service on Local Computer started and then stopped. Some services stop automatically if they are not in use by other services or programs."
The eWayTimerLog.txt file displays:

Check whether there is correct setting of Microsoft SQL Server in the web config including the instance name.
It can occur the error that there is set "localhost" instead of ".\PRODUKCE". Even though "localhost" works, eWayTimer cannot process it. You need to set it to ".\PRODUKCE".
