[Lazarus] Win64 bit "Can not load SQLite client library "sqlite3.dll"

[Dennis]

I was upgrading my FPC/Lazarus program from Win32 to Win64 bit.
It complied ok but when run, the debugger raised an exceptoin:
"Can not load SQLite client library "sqlite3.dll"

At first, I though it is because the existing sqlite3.dll is win32 
format so I went to https://sqlite.org/download.html to download 
https://sqlite.org/2017/sqlite-dll-win64-x64-3210000.zip
and replace the old sqlite3.dll with the win64 bite version.

However, now it does not an exception but just quietly quit without 
doing anything.

I think I might need another file called libmysql.dll but that is not 
available from https://sqlite.org/

I googled for it and found that an unknown site called 
www.dlldownloader.com has it but I am afraid to use it fearing it might 
be a virus infected file.

Does anyone know whether I need a 64bit version of libmysql.dll, if yes, 
where can I get it safely?

Thanks,

Dennis
