I tested letodb on Wine 1.5 with HMG.
there are 3 folders in the LETO\BIN\WIN\ subdir bcc, mingw, mingw64
bcc is Borland C 5.5
mingw HMG/Harbour 32-bit version on Windows 32-Bit
mingw64 Harbour 64-bit version on Windows 64-Bit
On a Windows 64-Bit System you need to take the mingw64 version.
Guess it is a service to be installed,so it needs 64-Bit compatibillity.
Therefore the mingw-Version won't succeed in 64-Bit.
