Windows 7 SECBASE.DLL is missing.

[FalseLogic]

Yesterday when I went to shut down my computer, I got an error box that said:

The program could not be started because SECBASE.DLL is missing from your computer.

The same error now appears on boot, and shows itself whenever logonui.exe, explorer.exe, or similar programs try to execute.

I can get to the point where I can log in to my account, and when I do, explorer will not start. I can't get task manager to start either.

Safe mode also wont work without this file.

I've only found a couple other places where people have this problem, but there was no fix, and it appears that SECBASE.DLL is not in anyone's W7 installation.

I'll try a system recovery, but I don't think it's going to work. I'll report back here either way, but if anyone has ideas, let me know.

Note: It IS SECBASE.DLL, not sccbase.dll.

The error message you encountered regarding the missing SECBASE.DLL file can cause issues with system functionality, including problems with logon and the execution of various programs. Here are some steps you can try to address this problem:

Steps to Resolve the SECBASE.DLL Missing Error:​

1. System File Checker (SFC):
   • Run the System File Checker tool to scan and restore missing or corrupted system files.
   • Open Command Prompt as an administrator and run the following command:

      sfc /scannow

   []Check Windows Updates:
   • Ensure your Windows system is up to date with the latest updates. Updates can sometimes replace missing or corrupted files.
   []Restore SECBASE.DLL:
   • If you have access to another Windows 7 system, you can try to copy the SECBASE.DLL file from that system to your computer. Ensure it's the correct version (32-bit or 64-bit) matching your system.
   []System Restore:
   • Since Safe Mode is also affected, you may try a System Restore to revert your system to a previous working state.
   • Boot into the Advanced Boot Options menu by pressing F8 during startup, then select "Repair Your Computer" and navigate to System Restore.
   []Repair Installation:
   • If the above steps don't work, consider performing a repair installation of Windows 7. This process can fix system files without losing personal files and applications.
   []Microsoft Visual C++ Redistributable:
   • Some programs may require the Microsoft Visual C++ Redistributable package. Make sure it's installed on your system.
   []Check for Malware:
   • Sometimes malware can cause DLL file issues. Run a thorough antivirus scan to ensure your system is clean.
2. Create a Bootable USB Drive:
   • If none of the above solutions work, create a bootable USB drive with Windows 7 installation files to access repair options.

     Additional Notes:​

     • Backup Important Data: It's always wise to back up important data before attempting any major changes to your system.
     • Monitor System Performance: Keep an eye on system performance and behavior even after resolving the issue to catch any lingering problems.
     Try these steps and let me know if you encounter any difficulties or if you need further assistance!
