今天安装NetAdvantageTM 2005 Vol. 3时老是报下面这个错：
error 1609,an error occurred while applying security settings.
aspnet is not a valid user or group.this could be a problem with the package,or a problem connecting to a domain controller on the network.check your network connection and click retry,or cancel to end the install.
解决方法：在【我的电脑】-【管理】-【本地用户和组】-【用户】下，创建名为“ASPNET”的用户，并将其设为Administrator.然后重新安装NetAdvantageTM 2005 Vol. 3就行。至于为什么要这样解决，我也没有弄明白，希望有知道的高人留言给我，小弟在这先谢了！
