Hey all, long time listener, first time caller I have been making an unattended XP install and everything is working except SAV10. It was working in previous builds, but now it is giving an error: of "Setup requires _setup.dll and _isres.dll (located in _setup.lib)" error, which usually means that either the setup can not expand into the %temp% folder or it is missing, and then continues. It seems to work fine after that. I have several application installs (including Office 2003, Acrobat 8, Novell client 4.91sp2, Groupwise 7, Zenworks...) that work just fine, this is the only app not working. I am using the RunOnceEx method using this as my command: REG ADD %KEY%50 /VE /D "Symantec AntiVirus 10.1.5.500" /f REG ADD %KEY%50 /V 1 /D "%systemdrive%\apps\Version10.1.5.5000\SAV10.msi REBOOT=ReallySuppress INSTALLSERVER=0 NETWORKTYPE=1 SERVERNAME=CRC-grouplink RUNLIVEUPDATE=0 ADDLOCAL=SAVMain,SAVUI,SAVHelp,QClient /qn" /f If or the life of me can not figure out why it would be giving this error. I have copied new "known good" setup files into the directory. If I start the silent install after I log in, it works fine, with no errors. there must be something simple I am missing...hopefully you smart people can point me in the right direction
