regsvr32.exe - application error

Hello,

I would like to inform that Regsvr32.exe Application Error
Codes are caused by misconfigured system files in your windows operating system or by the following reasons:

• missing or damaged or modified .dll files.
• Invalid Entry or Command path.
• Active X control errors.
• Registry issues.
• Viral or Malware Attack.

I suggest you to run SFC scan and check if it helps.

System File Checker is a utility in Windows that allows users to scan for corruptions in Windows system files and restore corrupted files.

Follow the below steps:

• Right click on the Start button, click on
  Command Prompt (Admin).
• Type “sfc /scannow” without the quotes and hit
  Enter.
• After the scan, restart the computer and check for the issue.

Reference: Use the System File Checker tool to repair missing or corrupted system files - Microsoft Support

Note: If you are not able to repair some files after performing SFC scan, I suggest you to refer to the point 3 “Windows Resource Protection found corrupt files but was unable to
fix some of them. Details are included in the CBS.Log %WinDir%\Logs\CBS\CBS.log”. Under the section “Run the System File Checker tool (SFC.exe)” to repair the corrupted files after performing SFC scan.

Hope this helps. Keep us posted on the status for further assistance.

Critical Error - After Update LogonUI crashes

Hello,

Thank you for posting your query in Microsoft Community.

I suggest you to boot into safe mode and check if the issue persists.

Safe mode is a troubleshooting option for Windows that starts your computer in a limited state. Only the basic files and drivers necessary to run Windows are started. The word
Safe Mode appears in the corners of your monitor to identify which monitors mode you are using.

To use a Safe Boot option, follow these steps:

• 
  Press Windows Key + R.
  
• 
  Run will open, type
  msconfig and hit the Enter key.
  
• 
  A system configuration box will pop up.
  
• 
  Click on Boot Tab.
  
• 
  Select or click the check box
  Safe mode with networking.
  
• 
  Click on Apply
  and ok.
  
• 
  You will then see a restart button. Click it to restart your computer.
  

Once you are in safe mode check if the same issue occurs.

Once you completed the steps above follow the below steps on how to go back to normal mode:

• 
  Press Windows Key + R.
  
• 
  Run will open, type
  msconfig and hit the Enter key.
  
• 
  A system configuration box will pop up.
  
• 
  Click on Boot Tab.
  
• 
  If you see safe mode box has a
  check mark in it, uncheck the safe mode box and hit
  apply or ok.
  
• 
  You will then see a restart button. Click it to restart your computer.
  
• 
  When your computer comes back up, sign in and you will now be in "normal mode".
  

If the issue does not occur in safe mode, then the issue might be related to drivers. I would suggest you to update your
graphic card drivers and check if it helps.



You can update drivers from the Device Manager.

• • Right click on start button and click on Device manager.
    
  • Select Display Drivers.
  • Right click on the Display drivers and select
    Properties
  • Click on the device tab and select Update driver.

If it doesn't help, try to install the latest drivers from the manufacturer website and check if it helps.

Let us know the status of the issue. For further assistance feel free to post your queries in Microsoft forums. We will be glad to assist you.


Thank you.
