Answer 1

Well thanks to sqlite3.exe command line tool, I've found out that there are some additional DLLs needed for this to run:

• libproj-0.dll
• libgeos-3-1-1.dll
• libgeos_c-1.dll

You can find these on SpatiaLite's download page. Just copy them to the bin directory.

UPDATE: one additional dll needed is libiconv2.dll
