I was working with Excel, and it crashed. I was forced to close the program and received “Run-time error ‘429’: ActiveX component can’t create object.” error. I thought it was a one-time problem. However, it has occurred few more times. Is there something wrong with my computer?
ActiveX error 429 belongs to the wide group of run-time errors. It usually occurs using various Microsoft Office programs, such as Word or Excel, in Windows 10, 8 or 7. The main reasons why this error is triggered might be:
corrupted registry entries;
deleted operating system’s files;
incomplete installation of the program;
corrupted system files;
corrupted program files;
malware attack.
If some of these problems occur, the Windows closes the currently running program and delivers an error message saying:
Many different issues can cause Active X Error 429, so there’s a bunch of ways to fix it.
Method 1. Scan the device for malware
Various computer viruses can damage system files, corrupt registry and cause other problems that trigger this error message. Typically, malware attack is followed by system slow downs and other error messages. Therefore, if you have noticed signs of the attack, you should scan the device with reputable malware removal tool, such as [d1]
Method 2. Reregister the program

1. Login to Windows admin account.
2. Open Run application by pressing Win key +R.

4. Click OK.

Windows 7: Open Start -> Type “cmd” in the Windows search box -> choose necessary result.
2. When in Command Prompt, enter the name of the corrupted file, for instance, regsvr32 Filename.ocx or regsvr32 Filename.dll.
3. Replace the filename with the specified title.
4. Click the Return key for file reregistration.
Method 4. Run the System File Checker
Corrupted system files might be the reason of ActiveX Error 429. In order to fix it, you have to run the System File Checker that is an inbuilt feature in Windows.
