Windows installer error on XP

[joneroc]

When I try to install com proxy applications the
following message appears. The Windows Installer Service
could not be accessed. This can occur if you are running
Windows in safe mod, or if the Windows Installer is not
correctly installed. The installer works with all other
application.

Hi,

Some of your Windows Installer files that are on your hard disk are damaged
or are missing.
