This sep install log are not giving much information. You can make sure that you are installing the 64 bit package & not 32 bit. You can right client the setup.exe & run it as administrator. This dose make difference.

Your Log Shows

 ""MSIASSERT - DefInstallCA: Failed to load ccInst64.dll. symRes=0x80010300:""

1.Make sure you are using a 64 bit package.
2.Again Export a new Package try installing that.
3.Make sure you have permission on C:\ProgramData

 Hi All,

Thanks for the reply. I am installing 64 bits package and able to install this package on the other Z800 workstation with the same specification.

At the end of the log, there is a "returning 1603" sentence. Is it a 1603 error? From this link "http://service1.symantec.com/support/ent-security.nsf/854fa02b4f5013678825731a007d06af/7f4e8b02283eab4d8025740f002bfe81?OpenDocument" , it say Windows
Script Environment is corrupted and need to reinstall. Do i need to reinstall the windows script environment for vista?

Cheers,
Ryan

1. Check if Event Log is Started and set as automatic  in services.msc. If this service is stopped, then,
2. Download eventlog.dll file and copy it in C:\WINDOWS\system32
3. Start the Event Log and install SEP11
