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
To resolve this issue, perform the steps in the "Reregister the Windows Installer service" section. If you experience the issue after you perform these steps, you may also have to perform the steps in the "Run System File Checker" section.


Reregister the Windows Installer service
The Windows Installer service manages the installation and removal of programs. The service applies a set of centrally defined setup rules during the installation process. These setup rules define the installation and configuration of the installed program. Windows Installer uses the Microsoft installation engine to install or remove programs. If the registration of the Microsoft installation engine is corrupted, you may not be able to remove programs that you have installed by using Windows Installer. In that case, you have to unregister and reregister the Windows Installer service. To do this, follow these steps:

1. Start your computer in Safe mode. To do this, follow these steps:
a. Restart the computer.
b. After the BIOS information is displayed, press F8.
c. Use the DOWN ARROW key to select Safe Mode, and then press ENTER.
d. Use the UP ARROW key and the DOWN ARROW key to select your computer, and then press ENTER.

2. Log on to the computer as local administrator.
3. Click Start, click Run, type cmd.exe, and then click OK.
4. At the command prompt, type msiexec /unregister , and then press ENTER.
5. At the command prompt, type msiexec /regserver, and then press ENTER.
6. At the command prompt, type exit, and then press ENTER to close the command prompt.
7. Remove the software program from Add or Remove Programs.


Run System File Checker
The System File Checker (Sfc.exe) utility is used for scanning protected operating system files to verify their version and integrity. If System File Checker detects any operating system file with the incorrect file version, it replaces the corrupted file with a file that has the correct version from the Windows installation source files.

To use System File Checker, follow these steps:
1. Click Start, click Run, type cmd.exe, and then click OK.
2. At the command prompt, type sfc /purgecache, and then press ENTER.

Note You may be prompted to provide Windows installation source files when you run the sfc /purgecache command. If the command is completed successfully, you will receive the following message:
Windows File Protection successfully made the requested change.
3. At the command prompt, type sfc /scannow, and then press ENTER.

Note This command may take several minutes to finish. You may also be prompted to provide Windows installation source files when you run the sfc /scannow command.
4. At the command prompt, type exit, and then press ENTER to close the command prompt.
5. Remove the software program from Add or Remove Programs.

Thanks, Dave:

Your answer is a copy of the Microsoft approach and helpdesk...

I don't like that, allthough I've a genuine OEM XP and Office copy on my PC, for which I paid a high price, they (and you) want me to validate!!!! Come on!!
Redicolous! I paid for this, and beyond my 'guilt' I got into trouble: so THEY (MICROSOFT) have to solve, free of charge, my problem!!

Thanks, Dave, anyway!

Either that or I paste the link to the page which the administrator of this site doesn't like people doing.

If you have a problem similar to the one you mentioned, try searching for it over the Internet instead of adding an entry to this forum.

Sorry Dave, for my frustrated reaction...
The Microsoft trick didn't work for me and I was hoping for alternative approaches that work. Who can help?

YESSS!! Found a solution (on the Lavasoft forum): downloaded Adaware SE from Major Geeks: and it works! Nice install, good operational and update.

Donot know what the difference is....

Did you download the program completely? Try right click and install?

Do you have problems installing anything else?

Why would it bother you to have to validate your installation of windows? If it's a legit version as you say it is, then you would have no problems validating and it would only take a couple minutes of your time. Your reaction here makes me a little skeptical...
