NT SP6 Windows Installer

I am upgrading SOS from 3.5.2 to 4.0.2 on our Windows NT SP6 server. I get the following message on double clicking SosServerProfessional_4_0_2.msi:

This installation package cannot be installed by the Windows Installer service. You must install a Windows service pack that contains a new version of the Windows Installer service.

How do I get around this? Thanks for the help.

Not all systems have the Microsoft Windows Installer.

First, be sure that you are installing from the local machine, not from a network drive.

Here are some links that might be useful:

One of our users had a similar problem when they tried to install our Vault product. This was his solution:

Error message was: "The Windows Installer service could not be accessed. This can occur if you
are running in safe
mode or if the Windows Installer is not correctly installed. "
This error is probably the result of a damaged registration service.

To resolve this issue:
1. Open a CMD.EXE prompt.
2. Type msiexec /unregister and press Enter.
3. Type msiexec /regserver and press Enter.
that is it ..
