Its not a good idea to place the sprouts.exe in with the wallet’s data directory. That is, your “roaming” directory that you show should not have the “sprouts” (the one with the logo for an icon) executable file. The “sprouts.exe”, along with those three dll files, should all be in a separate directory.
Also, I can see that your configuration file (the one that contains the “addnode” commands) is not named correctly. It should not be “sprouts.conf.dat” but rather it should be renamed as “sprouts.conf”.
