1. Take a look at Download.png
2. Install:
Standard Installer:
lazarus-1.8.2-fpc-3.0.4-win64.exe 2018-02-26 152.8 MB
Installer to compile x86 programs on windows x64 (optional):
lazarus-1.8.2-fpc-3.0.4-cross-i386-win32-win64.exe 2018-02-26 38.8 MB
3. After the installation go to: PROJECT -> NEW PROJECT -> SIMPLE PROGRAM
This way you can create easy FreePascal Programs and GUI Programs (LCL or LCL + ...).
That's what I would do...
PROGRAM HelloWorld;
USES
Crt;
BEGIN
ClrScr;
WriteLn('HELLO WORLD');
ReadLn;
END.
