Thanks Pascal. The sqlite3.dll is in the %WINDIR%\system32. If I'm not mistaken, all the 32 bit libraries are there. So it seems that there is no sqlite3-64.dll, since the content of the file you advised me to download doesn't call it by that name. It has the same name as the 32 bit version.
Ok. Aside from that issue, do I need to place a copy of the dll together with my project folders?
Attached is a screen shot of the tables that I have in my database. I imported the data from CSV files into SQLite. Do these tables need to be compiled or is importing the CSV files all that I have to do?
