The 1721 error is a big problem that's caused by the installation of a specific piece of software on your PC being damaged. This particular problem is mainly shown with the installation of "Microsoft Office", and can be caused by everything from a corrupt set of registry keys on your PC to the installation program being incorrect. The good news is that you can fix this error very easily by first using the "Windows Installer Cleanup Utility" to fix the errors your system has, as well as curing the various other errors your computer may have inside.
The first step to fixing the 1721 error on Windows 7 is to use the "Command Prompt" to unregister, and then re-register the Windows Installer application on your PC. Command prompt is like MSDos and can be loaded by pressing Start > Run, and then typing "cmd" into the box that appears. When in this prompt, you will be able to perform a lot of system-centric things, including un-registering the Windows Installer program. This is basically like uninstalling the software (which is not possible due to WI's importance on your system). You should type "msiexec u/unregister", and then "msiexec /register" to refresh the Windows Installer program on your system, allowing your PC to use it correctly.
The second step to repair the 1721 error on your PC is to then use a registry cleaner to correct any damaged or corrupted settings that Windows may have inside. Registry cleaner tools are software programs which are designed to scan through the 'registry database' of your PC and resolve any of the errors which are inside it. The registry database is a very important part of every Windows system, as it's where your PC will keep all the files and options that it needs to run. The 1721 error is often caused by the likes of the registry becoming damaged, preventing your system from being able to read the files it needs correctly. To resolve this problem, you should download and run a registry cleaner tool to ensure that all is working correctly with Windows.
