Microsoft word and excel logos have changed

Hello,

My microsoft word and excel logos have changed to some white looking logo. I've followed the instructions given on a previous thread (office-tools-picture manager-detect and repair) but this sign has come up "this patch package could not be opened. Verify that the patch package could exists and that you can access it, or contact the application vendor to verify that this valid Windows Installer patch pack package" Any idea what this means?

Thanks a mil!
