What causes error 1722 (Windows Installer package error)?

Here are some possible reasons for this error:

  • The Windows Installer is disabled in the system settings.

  • Some system files are missing or damaged on your computer.

  • Incorrect or corrupted registry entries conflict with the Windows Installer.

  • Some programs are corrupted.

1. Quick fixes

Before proceeding with detailed solutions, here are some quick fixes you can try.

  1. If an error occurs, restart the computer immediately.

  2. Update your apps. In addition to adding new features, updating applications helps to fix or remove system errors.

  3. Run the Windows Troubleshooter. Go to the Windows Start menu >PC Settings>Update and Security>Troubleshooting. Run both the Program Compatibility Troubleshooter and the Windows Store Application Troubleshooter.

  4. Clean up your computer. A simple disk cleanup helps free up disk space and allows applications to run efficiently. This can help solve problems with the Windows Installer and other programs.

2. Turn on the Windows Installer.

If Windows Installer is disabled, it will be difficult for you to install or uninstall programs. Here’s what you need to do to enable the installer.

  1. Press the Windows R keys to open the Run Command dialog box.

  2. Type services.msc and press Enter.

  3. On the next screen, scroll down and double-click the Windows Installer option.

On the next screen, set the Windows Installer Startup Type parameter to Manually. Click the Start button to turn on the service. Select Apply and then OK to save these changes.

3. Run the Microsoft Program Installation and Removal Troubleshooting Tool.

If you suspect that the problem is caused by corrupted registry keys, the troubleshooting tool for installing and removing Microsoft programs can help you.

When it comes to fixing corrupted registry keys, you should not use a registry cleaner. Running these programs can harm your computer. If you delete, move, or damage registry keys, critical system functions may fail. This could cause problems with installing, launching, or deleting applications.

The troubleshooting tool for installing and uninstalling the program will not only help scan and fix corrupted registry keys, but also fix other system files.

  1. To get started, download Troubleshooting when installing and uninstalling the program.

  2. Run the troubleshooter by double-clicking it.

  3. Click Next to start the troubleshooting process.

  4. From the options that appear, select the option ‘Install’ or ‘Uninstall’.

In the next window, select the program you are having problems with and click Next. If you can’t find the program in the list, select the option Not in the list and find the program. From here, follow the on-screen instructions to complete the troubleshooting process.

4. Cancel the registration and re-register the Windows Installer.

  1. Press the Windows R keys to open the Run Command dialog box.

  2. Type CMD and press Ctrl Shift Enter to open an elevated command prompt.

  3. To temporarily unregister the Windows Installer, type the following command and press Enter:

msiexec / unreg

After completing this process, you can re-register the Windows Installer. To do this, type the following command and press Enter:

msiexec / regserver

Restart your computer to save these changes.

5. Use the SFC and DISM tools.

Since this error can occur due to corrupted system files, you can fix it using the SFC and DISM tools. SFC will scan your computer for missing or corrupted system files, and DISM will scan the system image used to make these fixes. In this case, you should run DISM first to make sure that the SFC is working correctly.

  1. To get started, press Windows R keys and type CMD.

  2. Press Ctrl Shift Enter to open an elevated command prompt.

  3. Type the following command and press Enter:

DISM / Online / Cleaning-Image / ScanHealth

When the scan is complete, type the following command and press Enter:

DISM / Online / Cleanup-Image / RestoreHealth

Wait for the scan to complete, and then restart the computer.

Open the command prompt as described above. Type the following command and press Enter:

sfc / scannow

Wait for the scan to complete. From here, close the command prompt and restart the computer.

6. Install programs in safe mode.

You can solve this problem by installing the software in safe mode. This will help you determine if the problem is caused by installed software or damaged hardware components of your PC.

If you no longer encounter the error as soon as you boot into safe mode, it’s safe to say that the problem is due to the driver or software.

  1. To get started, go to the Windows Start menu >PC Settings>Update and security.

  2. Select the recovery option.

  3. In the ‘Advanced Startup’ section, click the ‘Restart Now’ button.

This will restart your computer in the recovery environment.

On the screen that appears, select ‘Advanced Options’>'Startup Options’ and click ‘Restart’. Finally, press the F4 key to make your computer boot into safe mode.

7. Perform a clean boot and use a third-party uninstaller.

You can perform a clean boot to isolate other programs that may be causing this error. This process simply boots your computer with all third-party applications disabled. It also runs your computer with the minimum necessary drivers and programs. This helps to eliminate any conflicts that arise during the installation or removal of the software.

Once you have identified the problematic program, you can uninstall it using a third-party uninstaller. This will help to make sure that there are no residual files that can cause further problems on your computer.

If nothing helps, you should consider upgrading Windows. This should help solve this problem and other important system problems.
