|Two thing you could try:|
On the Windows Task Bar:
first select Tools - Folder Options - View
and select Show All Hidden Files
then un-check: Hide protected system files
and also: Hide extensions of known file types
Next go to the \Windows\Installer folder.
In the \Windows\Installer browse all the MSI files which are Windows Installer Packages and look for the installer for Microsoft Works.
If you find it click on it and it should proceed with the setup of Microsoft Works
If that does not work, one other option:
Click the Start button
Click on Command Prompt
A small DOS type window should appear,
on the command line enter:
DIR /S C:\WORKS9.MSI
this will search your hard drive for the file.
I'm not 100% sure of the file name so you could also do use the command:
DIR /S C:\*.MSI
This will return all the MSI files it finds.
If both options fail, give Microsoft a call and explain what happened, they may be able to offer some assistance.
You will probably need all the numbers off your computer.
