:confused: I have been trying to reinstall Earthlink Total Access 2005. When I try to install, I get the message: Error 1721: There is a problem with the Windows Installer package. A program required for this install could not be run.
Does anybody know what this error refers to and how to correct it? Thanks in advance.

Are there any more details to the error -- which program failed to run?

Does the Earthlink install configuration allow you any options on what to install? By simplifiying it you may succeed.

Since this error seems to reference the "Windows Installer" which is separate from the Installshield engine, I would probably try updating that:

I don't know how helpful this will be: http://support.installshield.com/kb/view.asp?articleid=Q107579

You can update the installshield engine by following the directions on this page:

Try this:

For Windows 98:

- Click Start - Run, type command , and then press ENTER.
- At the command prompt, type cd \ and press ENTER so that you are at the C:\> prompt.
- Now type cd windows\system and press ENTER so that you are now at C:\Windows\System>
- At the command prompt, type msiexec /unregister , and then press ENTER.
- At the command prompt, type msiexec /regserver, and then press ENTER.

Reboot for safe measure.

Then try the reinstall.

:) I followed Rollin'Rogs suggestion. I'm not sure that's what did it because shortly thereafter my connectivity problem surfaced. Anyway everything is OK now and thanks again.
