Question about Dell Computers & Internet
The 1721 Windows error will show like this:
* Error 1721. There is a problem with this Windows Installer package. A program required for this install to complete could not be run. Contact your support personal or package vendor.
The cause of this error is because your PC cannot read the files / programs it requires in order to complete the installation on your system. Every time you install a program on your PC, a large number of files are basically copied from the installation program to your hard drive. This means that if you are trying to install a program, you first need to make sure the installation file is complete

Here you go. This is long winded but should fix you up.
Error 1721 is a common problem for many different Windows systems, shown when the installation you're trying to perform develops a problem and needs to be fixed. If you have this error, it's recommended that you're able to first fix any problems that could be inside your Windows system, and then cure the specific issues that the Windows Installer program has on your PC. This tutorial is going to show you exactly how to do that...
This error will typically show like this:
The problem with this error is actually caused by a very simple issue - the Windows Installer program that is used to install the various files & software onto your PC is actually damaged or corrupted & preventing your system from installing the program you want. This can be caused by a number of problems, including everything from having corrupt registry settings to the Installer program on your system being damaged. To fix this, you first need to make sure that Windows Installer is okay, and then get rid of any further system errors on your computer.
The first step to resolving this error is to "register" and "unregister" the Windows Installer on your system. This is a program which installs all the programs that you want onto your PC, and is constant on every Windows installation. The problem that often causes error 1721 is the way in which Windows often cannot read the Windows Installer program, because it's not "registered". Registering a program basically tells Windows where to look for it on your system, and it's often the case that this stored reference is either damaged or deleted by accident. To ensure this is not a problem, you need to be able to type the following into your system:
If you try this and find it does not work, then it's recommended you then use a program by Microsoft called the "Windows Installer Cleanup Utility". This is a new program which basically cleans up all the settings and options associated with the Windows Installer program; meaning that if you have any problems with the Windows Installer on your PC, they should be fixed. You may also wish to install Windows Installer 4.5, which will basically upgrade the Windows Installer program on your system, which should resolve many cases of the 1721 error.
It's also highly recommended that you use a "registry cleaner" to fix any of the errors that are on your Windows system. A registry cleaner is a type of software tool that basically scans through the registry database of your PC and fixes any of the problems that are inside it. The registry database contains all the settings, files and options for Windows, and is where everything from your most recent emails to your desktop wallpaper are kept. It's basically like a library for your system which is continually being used to help your software run correctly. Unfortunately, the registry is continually being damaged & corrupted, leading it to become highly ineffective and erroneous. To ensure this problem is not causing the 1721 error, you should clean through your system with a registry cleaner tool.
