If you encounter difficulties using either resolution, you may contact our web chat or phone support at 866-622-3911. Please note call volumes are high.

WinXP-4500c これはDATは6814でネット障害なし、8/28時点では6817と問題なし
WinXP-XPS-M1210 これはネット障害があり、メールにしたがって対応。6809になり、8/28時点では6817と問題解決
Win7-XPS 9000 これはネット障害はなかったが、8/28時点でも6807のまま。DATの更新ではエラーに。そこで上記の英語の解決方法2で6809に、さらにDATの更新で8/28時点では6817と解決した。
