Here are some easy ways to troubleshoot Symantec Endpoint Protection error 1603.
Error: “SEP Installation Failed, Error Code 1603”
Updated:
Products
Endpoint Security
Problem / Introduction
- Symantec Endpoint Protection (SEP) installation fails with buffer full on Windows 7 and Windows 10
Reason
- The SYSTEM account may not have sufficient permissions on the target file for the Windows Installer package. The Windows Installer service uses the SYSTEM account, which applies to software.
- There is no fancy MSI installer on the system.
- Not all TEMP and TMP system variables are set to the standard path C: windows temp.
- In most cases, Windows Defender should be disabled automatically by installing SEP. However, on rare occasions, some Windows Defenders will stay and block this particular SEP installation.
- System problem / possible damage to the operating system
Permissionse
- Confirm and provide the required authorization for the account.
- Make sure the current version of the MSI installer is installed on the device.
- Set the path to the TEMP and TMP system variables to C: windows temp
Windows Defender must be manually disabled. But the disable option is grayed out in the Windows List Service.
In Windows 10 Enterprise Edition, Windows Defender for GPO can be disabled.
There should be no GPOs in Windows 10 Home Edition, the only way to get rid of them is by editing the registry.
- win + r, enter “regedt32” time for open registration ›
- you will find the “HKEY_LOCAL_MACHINE SOFTWARE Policies Microsoft Windows Defender” hive
- Right-click in the right window and select New> DWORD (32-bit) Value.
- Name “Evaluation DWORD (32 bit)” as “DisableAntiSpyware” , and set the value to a value of 1.
- Confirm and restart your computer.
