有没有办法从Inno安装脚本内部生成新的GUID？
解决方法
在innosetup新闻组存档中找到这个：

我没有测试过.
[Code]
type
TGUID = record
D1: LongWord;
D2: Word;
D3: Word;
D4: array[0..7] of Byte;
end;
function CoCreateGuid(var Guid:TGuid):integer;
external 'CoCreateGuid@ole32.dll stdcall';
function inttohex(l:longword; digits:integer):string;
var hexchars:string;
begin
hexchars:='0123456789ABCDEF';
setlength(result,digits);
while (digits>0) do begin
result[digits]:=hexchars[l mod 16+1];
l:=l div 16;
digits:=digits-1;
end;
end;
function GetGuid(dummy:string):string;
var Guid:TGuid;
begin
if CoCreateGuid(Guid)=0 then begin
result:='{'+IntToHex(Guid.D1,8)+'-'+
IntToHex(Guid.D2,4)+'-'+
IntToHex(Guid.D3,4)+'-'+
IntToHex(Guid.D4[0],2)+IntToHex(Guid.D4[1],2)+'-'+
IntToHex(Guid.D4[2],2)+IntToHex(Guid.D4[3],2)+
IntToHex(Guid.D4[4],2)+IntToHex(Guid.D4[5],2)+
IntToHex(Guid.D4[6],2)+IntToHex(Guid.D4[7],2)+
'}';
end else
result:='{00000000-0000-0000-0000-000000000000}';
end;
function InitializeSetup(): Boolean;
begin
MsgBox(GetGuid(''),mbInformation,MB_OK);
Result := False;
end;
