"Endpoint Mapper Database entry not created"

Question

Original title: Windows 8.1 won't open taskmanager, command prompt, event viewer, etc.

As the title says. I can't install programs, I can't open task manager to end processes, I can't do much other than use the internet. The error that always appears is "Endpoint Mapper Database entry not created". I also can't run programs as an administrator. The only change I've made to my computer recently is editing the FirewallAPI.dll file in system32. Chew me out later for being dumb enough to try and edit a file in there. Can someone please help me fix this? If you can't I'm sorry for wasting your time.

Answer 1

Hi,

As you are unable to install any program probably the files responsible for the program or application installation might be corrupt. Yes, Windows 8 disc can be used for the repair of Windows 8.1.

Windows Defender Offline Beta can help remove hard to find malicious and potentially unwanted programs using definitions that recognize threats. Definitions are files that provide an encyclopedia of potential software threats. As new threats appear daily, it's important to always have the most up-to-date definitions installed in Windows Defender Offline Beta. Armed with definition files, Windows Defender Offline Beta can detect malicious and potentially unwanted software, and then notify you of the risks.

Note: We recommend that you download Windows Defender Offline Beta and create the CD, DVD, or USB flash drive on a PC that isn't infected with malware—the malware can interfere with the media creation.

Note: There could be a loss of data while performing a scan using Windows Defender Offline to eliminate virus if any.

Thank you.

The command prompt states that in order to run DSIM, I need to run it with elevated permissions. Attempting to run it as an administrator leads to it giving the endpoint mapper database entry not created error. Someone reccomended that I use the windows repair function on my Win8 install disk, will it work since I'm using windows 8.1?

Answer 4

Safe mode didn't work. The software needed to clean boot comes up with the endpoint mapper database entry not created error. The Microsoft Safety Scanner doesn't install since any attempt to install software leads to the same error mentioned earlier. The system restore won't work and instead comes up with the aforementioned error as well.

Answer 5

Hi Kristian,

The issue might have occurred due to the change you have made on the computer. Follow these methods to troubleshoot the issue:

Method 1:

Step 1:

I would suggest you to restart the computer in **safe mode** wherein the computer starts with basic drivers and no third party programs. Check if you are able to login to the user account.

Step 2:

If the issue doesn’t occur in Safe mode, you may try to restart the computer in a **clean boot** mode to check if any third party application is causing the issue, as clean boot helps in eliminating software conflicts.

Note: After troubleshooting, refer to the section “How to reset the computer to start normally after clean boot troubleshooting” to return the computer to a Normal startup mode.

Method 2:

I would suggest you to run Microsoft Safety Scanner for any spyware or malware infection:

Note: The Microsoft Safety Scanner expires 10 days after being downloaded. To rerun a scan with the latest anti-malware definitions, download and run the Microsoft Safety Scanner again. Any data files that are infected may only be cleaned by deleting the file entirely, which means there is a potential for data loss.

Method 3:

As the issue occurred recently, I would suggest you to back up the data and perform a system restore to an earlier point of time before the issue occurred:
