The Windows OS is no stranger to errors. If you’re a long-time Windows user, you probably already know what we’re talking about. Blue screen of deaths, disk failures, system file errors, and similar errors are rampant in the Windows environment.

Another one of those crippling errors, which mires the normal operations of Windows, is the infamous 0x8007012a Install Error. A rather peculiar bug, the 0x8007012a Install Error, is what prevents your PC from downloading and installing new updates. Here, we've laid down some basic ways you can get rid of the 0x8007012a Install Error in Windows.

1. Reboot Your PC

Some problems can be solved without going into too much complexity. In fact, you’d be surprised how rebooting a device—be it a smartphone, a computer, or even a device like a tablet—can rescue you from all kinds of troubles.

So, as a general rule, it’s a good idea to give restarting a shot before you dive into more obscure fixes; unless the reboot itself won't happen.

2. Run the Windows Update Troubleshooter

The Windows Update Troubleshooter, as the name suggests, is a troubleshooter to help you fix all the errors you might face during downloading and installing a Windows update. It is an in-built tool from Microsoft, available for free. It is, in fact, the number one solution to fix your Windows update errors that we've also covered before.

To fix the 0x8007012a Install Error, here’s how you can use the Windows Update Troubleshooter:

  • Go to the Start menu search bar, type in ‘settings,’ and select the Best match.
  • In the Settings menu, go to System > Troubleshoot > Other Troubleshooters.
    troubleshooter settings
  • From there, run the Windows Update troubleshooter.
    windows update troubleshooter

As soon you do that, a new dialog box will pop open, running all the checks and scans for trouble with your Windows update. Restart your PC after the troubleshooter is finished.

The 0x8007012a Install Error should ideally be resolved by now. To check if it worked, go to Windows Settings again and from there, select Windows Update > Check for updates. If everything worked smoothly, you shouldn't face any problem with installing the updates now.

3. Check the Background Intelligent Transfer services

Background Intelligent Transfer Service, or BITS for short, is a Windows tool that lets you download or transfer your files between computers over the internet. So if this component of your PC is turned off, naturally, there's going to be trouble downloading new updates. To make sure that's not the case, follow the steps below:

  1. Go to the Start menu search bar, type in ‘run,’ and select the Best match. Alternatively, press Win + R.
  2. In the Run dialog box, type in ‘services.msc,’ and hit Enter. The Management Console will be launched.
  3. Search and locate the Background Intelligent Transfer Service. Then double-click on it.
  4. In the new dialog box, set the Services Status to Start if it isn’t already.
