I have just downloaded and installed your latest Beta version.
Given that it has no code function like
[Code]
function GetAppFolder(Param: String): String;
begin
  if InstallOnThisVersion('0,6', '0,0') = irInstall then
    Result := 'C:UsersPublic'   ExpandConstant('{username}')
  else
    Result := ExpandConstant('{pf}');
end;
 
Then is it the case that I should use this new version only for Vista and the old version for XP and below ?
 
Or can only one install routine be used for all versions of windows just like it could before this latest beta update ??
