Hello,
Checking the Logs more in detail
We Found Failed Errors -
MSIRESULT !!FAILED!! - CheckExistingCCInstalledApps: Unable to open key. Return:2:
LUCA: CheckForRunningLU: Failed to open LU mutex, can not check for running LU.
AgentMainCA: ERROR: MsiEnumRelatedProducts failed with error 259
Try checking Permissions for the InstalledApps registry key (HKLM\Software\Symantec\InstalledApps) may be incorrect.
The permissions may also be wrong on HKLM\Software\Symantec\Common Client\
It could also be resolved by uninstalling the client, deleting the faulty registry keys, and reinstalling.
If there are other Symantec products on the system, you could just adjust the permissions on the keys as well.
These keys should have System, Creator Owner, Administrators, and Users (read)
Also TRY:
One possible solution is to use a silent install package and pass it force options. (the force options do not work with interactive, or unattended installs - ONLY with silent)
msiexec.exe /i symantec antivirus.msi /q /forcerestart
OR
Using the SEPM, create a client install package:
Add Client Install Settings:
Set to Silent install
Restart after installation
Upgrade settings - Remove all previous logs
Add Client Install Feature set:
AV/AS
NTP
PTP
Export Package:
Set export path
Include Client Install Settings / Client Install Feature set
Select client group
Click ok to export package
Copy export package to client machine -
Open Task manager to search for msi's due to silent install
Wait for the icon to appear in the system try and view the SEP_Inst log.
The installation is successful but the client may never go for reboots.
