This page applys to XP,

http://support.microsoft.com/kb/891985

but the solution should be similar. If you've done the registering, the next suspect would be something corrupt in your VPN package.

Try a fresh download or copy of it, and be sure you run as administrator during the install.

Am getting 1721 errors on my computer, can you tell me how i can fix it ?


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:

  • 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 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:

  • Load up "CMD" (click "Start" > Run > type cmd)
  • Type msiexec u/unregister
  • Type msiexec /register
  • Try reinstaling the program you wanted to

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.

Cisco VPN Client for 32 bit vista


Download the latest version of the Cisco VPN Client. My version is 5.0.03.0530.

You can also try using the Microsoft "MSIZap" utility to ensure a clean uninstall. It is a command-line utility. You will need the original MSI install file from the Cisco VPN client to use MSIZap.

You can download it here: http://msdn.microsoft.com/en-us/library/aa370523.aspx

Error 1721


What Is Error 1721? This is an error commonly witnessed when you try to uninstall a program using the "Add or Remove Programs" in Microsoft Windows XP. The message itself will read: "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."
Resolution #1: Reregistering the Windows Installer service It is known that if the Microsoft installation engine malfunctions or is internally corrupted, there is a possibly that you will not be able to remove programs that you used the Windows Installer, the service that administers the installation and configuration of programs, to install with. Thus, in the case of error 1721, it is necessary to unregister and then reregister the Windows Installer service to fix the corrupted parts of the engine. This can be accomplished through the Safe Mode by:
  1. Enter your computer in Safe Mode by:
    • Restarting the computer and pressing F8 after the BIOS information is shown
    • Select Safe Mode and Enter
    • Select your computer and Enter
  2. Log on as the local administrator
  3. Open up the command prompt by clicking Start, Run, and then typing cmd.exe and Ok
  4. At the command prompt, first unregister the service by typing msiexec /unregister and then hitting Enter
  5. Reregister the service by typing msiexec /regserver and then hitting Enter
  6. Type Exit to exit the command prompt safely
  7. Try to remove the program once again using Add or Remove Programs
I hope this helps you out. Thanks

Error 1721


Try the following regardless of the software as this is the common error message provided by Microsoft. Of course this won't rule out either a corrupt installer or incompatibility's
  1. Disable/Configure any anti-spyware or anti-virus software on your system during installation process. For example: Spybot Search and Destroy Program or Norton Anti-Virus
  2. Check to see if any spyware or adware is installed on your system blocking the completion of install process.
  3. Check to see if you find any unwanted entry in Add/Remove Programs or Internet Explorer - Add/On's section (Tools - Internet Options - Programs -> Manage Add On's). If you found one, remove/disable this entry.
  4. On Windows Vista, disable UAC (User Access Control) feature for your account
