いつもいつもありがとうございます！！

OSVERSIONINFOEX構造体も、6.0と.NETでは、中身が違うんですね〜
最初は6.0で書いていたのですが、コンパイルできなかったので.NETに変えちゃいました(6.0の方が使い慣れているんですよね〜)。

ちなみにこんな感じで、取得させてみました。
	OSVERSIONINFOEX ovi;
	//OSのバージョンを取得
    ovi.dwOSVersionInfoSize = sizeof(OSVERSIONINFOEX);
    if(GetVersionEx((LPOSVERSIONINFO)&ovi) == FALSE)
	{
		sprintf(OSVersion, "OSのバージョン情報取得に失敗しました。");
	}
	else
	{
		//Windows95/98系
		if(ovi.dwPlatformId == VER_PLATFORM_WIN32_WINDOWS)
		{
			//Windows 95
			if(ovi.dwMinorVersion == 0)
			{
				if(ovi.wServicePackMajor == 0)
				{
					sprintf(OSVersion, "Microsoft Windows 95");
				}
				else
				{
					sprintf(OSVersion, "Microsoft Windows 95 with Servise Pack %d", ovi.wServicePackMajor);
				}
			}
			//Windows 98
			else if(ovi.dwMinorVersion == 10)
			{
				if(ovi.wServicePackMajor == 0)
				{
					sprintf(OSVersion, "Microsoft Windows 98");
				}
				else
				{
					sprintf(OSVersion, "Microsoft Windows 98 with Servise Pack %d", ovi.wServicePackMajor);
				}
			}
			//Windows Me
			else if(ovi.dwMinorVersion == 90)
			{
				if(ovi.wServicePackMajor == 0)
				{
					sprintf(OSVersion, "Microsoft Windows Me");

					sprintf(OSVersion, "Microsoft Windows Me with Servise Pack %d", ovi.wServicePackMajor);
				}
			}
			else
			{
				sprintf(OSVersion, "OSのバージョンが不明です(Windows 95系)。");
			}
		}
		//あまりあり得ないが、Windows3.1系

細かく・・・とか言いながら、けっこういい加減です（笑）。
おかげで助かっちゃいました☆
ありがとうございます。
