Error code:1706 installation package "ProPlus.MSI" to be installed from XP CD Rom

Any one know what this is? I can't access any Excell files, keep getting the message to run the CD Rom with XP Professinal FrontPage to allow the program to run.

 

Error code:1706. Installation Package "ProPlus. MSI"

 

This is stopping me from opening any excell files.

 

I am just out of warranty, is this a coincidence for this problem to manifest itself after expiry?

 

Any solutions?

 

Thanks.
