Utilities 14: Missing files unins000.msg, map.dat, values.dat & keys.dat

I want to do an uninstall/reinstall of my Utilities 14. Using Windows 7 Add/Remove Programs tool I get the following message: "Messages file '*\Norton Utilities 14\unins000.msg' is missing. Please correct the problem or obtain a new copy of the program."  I've redownloaded the software but when I try to reinstall, I get a message that says I can't install the software until I've uninstalled the existing program. I also get the following error message:  "Norton Utilities is missing core application files:  '*\Data\map.dat, *\Data\values.dat, and *\Data\keys.dat.'  Please reinstall."

 

I've seen other similar posts (in fact, the above is a partial cut and paste from an earlier post)  but the solutions aren't clear to me.  Any advice would be appreciated.

 

Thanks
