Issue



Using MSI command line switches (" /S /v "/qn /quiet /passive /norestart ENABLEAUTOPROTECT=0 SYMPROTECTDISABLED=1 RUNLIVEUPDATE=0 REBOOT=REALLYSUPPRESS"), the SEP client installation either fails entirely, or does not abide by the switch parameters.

These switches worked with SEP 11.x and with previous Symantec AntiVirus (SAV) 10.x installations. 

 


Error



Can vary. Most frequently, the install simply does not complete.

 


Environment



Following is a sample of the MSI command line switch code used to install the SEP 12.1 client when the installation fails. (Note: an installation from network share has never been recommended.)

"\\some_network_share_path\setup.exe<file:///\\some_network_share_path\setup.exe>" /S /v "/qn /quiet /passive /norestart ENABLEAUTOPROTECT=0 SYMPROTECTDISABLED=1 RUNLIVEUPDATE=0 REBOOT=REALLYSUPPRESS"

 


Cause



Verify that you are not using a command line switch that is no longer valid. 

 


Solution



SEP 12.1.x makes the following changes to MSI command line switches:

  • SYMPROTECTDISABLED is no longer used.
  • REBOOT is no longer used; instead, use SYMREBOOT. The syntax is exactly the same.
  • CACHEINSTALL is no longer used; instead, use CACHE_INSTALLER.
