Install is not possible with Delphi XE and below as the Class "Sytem.AnsiStrings" in file "ALFcnString.pas" seem to be unknown. Looks like it was integrated in XE2.
function ALPosEx(const SubStr, S: AnsiString; Offset: Integer = 1): Integer;
begin
{$IFDEF UNICODE}
Result := System.AnsiStrings.PosEx(SubStr, S, Offset);
I'll look at it later or does anybody know what to do?
Just delete the Sytem infront of System.AnsiStrings.
