I tried the below function but it didn't work.

if ComponentsList.Checked[2] then
 begin    
 if not ISExec ( 0, 0, 0, ExpandConstant('{tmp}\Patch.exe'), ExpandConstant('/Dir={app}'), ExpandConstant('{tmp}'), '...',false) then break;
end;

please help.

Try this

if IsComponentSelected('NAME') then begin
[Your Code]
End;
