  • 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 hasn't 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 by downloading, unzipping (password panda) and running the file: rootsupd.exe process from here.

          NOTE I: The rootsupd.exe file is the one used by Microsoft but has been officially withdrawn from their download site because Windows XP is no longer supported. Please use it under your responsibility and contact Microsoft for help if you have any questions.

          NOTE II: We strongly recommend to verify that the operating system is not blocking the execution of the rootsupd.exe file. To do so, go to the Properties of the file and if the option appears, unblock the file.

          If you don´t unblock it, it will not be possible to run the file but what's more, the system will not inform that the file has not been run either.
    • 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
