这是SPSS Amos 20.0 官方最新的补丁包，修正以下问题：

Issues corrected since SPSS Amos 20.0 Release

1、Path diagrams saved by AMOS 20.0 can now be opened in earlier versions.
2、Installing AMOS 20.0 FixPack 1 will now preserve the DaemonHost value in spssprod.inf when applied to network-licensed installation provided install is done with full admin rights (XP) or right-click->Run As Admin (Vista, 7).  If insufficient rights are present, a warning will be displayed on completion of the install, and a backup copy of spssprod.inf named  "spssprod_amos20.0.inf" is saved to the user's My Documents folder.  Simply manually copy the backup into the AMOS install directory and rename back to "spssprod.inf".
3、Successive runs of Models with missing data no longer return negative chi-square values in certain regional locale settings.
