So I downloaded the fpspreadsheet 1.6 and I have an error with my application when I'm compiling. It's like if the fpstypes.pas can't be recognize by lazarus... I tried to unistall fpspreadsheet and launch a new installation but I can't solve my problem. So I'm there and I hope that you coule help me !
