我的程序安装了一个驱动程序，它有为XP、Win2003、Vista/Win2008和Win7编译的不同版本。我使用pascal函数来检查哪个是操作系统，并安装相应的DLL。

在一些用户的系统上没有安装 DLL，这意味着所有的函数都返回了 false。只要操作系统的主要版本是 5 或 6，就不会发生这种情况。

谁能告诉我我使用的代码是否有问题？

[Code]
function UseDriverForWindows7(): Boolean;
var
  Version: TWindowsVersion;
begin
  GetWindowsVersionEx(Version);

  // Windows 7 version is 6.1 (workstation)
  if (Version.Major = 6)  and
     (Version.Minor = 1) and
     (Version.ProductType = VER_NT_WORKSTATION)
  then
    Result := True
  else
    Result := False;
end;

function UseDriverForWindowsVistaAndWindows2008(): Boolean;
var
  Version: TWindowsVersion;
begin
  GetWindowsVersionEx(Version);

  // Anything with major version 6 where we won't use Windows 7 driver
  if (Version.Major = 6) and
     (not UseDriverForWindows7)
  then
    Result := True
  else
    Result := False;
end;

function UseDriverForWindows2003(): Boolean;
var
  Version: TWindowsVersion;
begin
  GetWindowsVersionEx(Version);

  // Windows 2003 version is 5.2 (server)
  if (Version.Major = 5)  and
     (Version.Minor = 2)  and
     (Version.ProductType <> VER_NT_WORKSTATION)
  then
    Result := True
  else
    Result := False;
end;

function UseDriverForWindowsXP(): Boolean;
var
  Version: TWindowsVersion;
begin
  GetWindowsVersionEx(Version);

  // Anything with major version 5 where we won't use Windows 2003 driver
  if (Version.Major = 5) and
     (not UseDriverForWindows2003)
  then
    Result := True
  else
    Result := False;
end;

您应该使用公共参数 MinVersion并OnlyBelowVersion与函数结合使用IsWin64。

要区分工作站和服务器版本，您可以使用GetWindowsVersionExInno Setup 中集成的功能。
