Error 2081 installing the protections in Endpoint Protection

Ces informations s’appliquent à:

Panda Cloud Office Protection
Panda Cloud Office Protection Advanced


Error 2081 occurs installing the protections in Endpoint Protection.


This error is caused by one of the following causes:

  • The agent does not complete the installation correctly and the .msi file is launched. An error is returned on launching a second .msi file.
  • The installer has been corrupted by the firewall (by GateDefender or a similar protection that can eliminate a file in the .msi installer).


Panda Security has developed 2081Fix.exe tool to solve error code 2081. Follow these steps:

  1. Download and execute the 2081Fix.exe tool.
  2. Follow the actions requested by the tool: check Administrator rights for fixing a given problem or reboot the system, for example.

    Note: Sometimes it's necessary to reboot the system and wait for 2081 error to appear. Then, execute the 2081Fix tool.

Additional checks to carry out to confirm or rule reasons out

Should error 2081 persist, check the following tests to confirm or rule reasons out.

Go to Start -> Programs and make sure there is NO other antivirus installed that can be automatically uninstalled. Check the Which programs are uninstalled automatically by Endpoint Protection? help.

  • Check 1: Root Certificates

    Check the GlobalSign root certificates are in place and if so, that they have not expired. To do so, use Certificate Manager.
    Steps to check it:
      • Run certmgr.msc
      • Expand Trusted Root Certificates and then click on Certificates.
      • Check if GlobalSign and Global Sign Root CA exist and that the expiration date has already passed.
  • Check 2: Proxy or Firewall corruption

    Review your firewall/proxy logs to find out if there is any Panda file being blocked.
Additional solutions

Apply the solution that corresponds to your case:

SOLUTION 1: Update Root Certificates

  • Method 1: Install/Update ONLY the required installation certificates.
        • If you system is a Windows XP, you have to download certutil.exe tool:
          • The only version of certutil.exe that Windows XP supports is available in the Microsoft Windows Server 2003 Administration Pack. Access the Microsoft website to download it.
          • If you have update 907247 installed on Windows XP SP2, the version of certutil.exe that supports the -pulse command is available in the SP1 version of the Windows Server 2003 Administration Pack.
            To download it, visit the Microsoft website.
      • Open a CMD window with administrator rights and install the root and intermediate certificates:

        certutil -addstore Root Root-R1.crt
        certutil -addstore CA gscodesigng2.crt
  • Method 2: Install/Update all system certs
    • Steps for Windows XP
        • Under Control Panel, go to Add & Remove programs.
        • Click on Add/Remove Windows Components.
        • Check Update Root Certificates.

          If this option is already checked and the error persists, there must be a Windows issue downloading update root certificates (check for crypt32 errors in Event Viewer, Application).

          If you do not want to enable the Update Root Certificates, or fails downloading them, root certificates can be updated manually downloading and running the file: rootsupd.exe process from Windows Update.
    • Steps for Windows Vista/7/8
        • Open a cmd window with administrator privileges and go to extracted file path.
        • Execute the following command: CERTUTIL.EXE -f authroot.stl
        • Retry the installation.

    SOLUTION 2: Other scenarios

    Open a cmd with administrator privileges and then execute the following command: CHKDSK C: /F /R
