I tried to install railblocks wallet for gaining Mrai coins in my 64 bit i5 laptop,but the msg 'ddl files not found,reinstall again' appears.I tried many times, but same problem.Pls give your valuable suggestions.
A DDL file is a SQL Data Definition Language file. Make sure you have the latest version of SQL-server and than try again to reinstall the Raiblocks. There is a new version of it 7.7.0 which has some minor improvements.
Uninstall Raiblocks(if it has created some folders by any chance), delete all it's program folders, if you can't then use a powerful cleaner like CCleaner which is free.
After doing so, try reinstalling Raiblocks, should work now.
