Office 2013 HUP, failed install, can't verify the signature.

[News Bot]

This is the error message, preventing installation...

"We're sorry, but we can't verify the signature of files required to install your Office product.

We need to verify these signatures to keep your computers safe.

Please retry installing your product or, if installation continues to fail, try

re-downloading your installer if you go it online. Make sure you only download

Office products from a trusted source"

This is happening after the first install failed part way through. Couldn't re install due to this error and have tried multiple fixes from Microsoft. This is still happening. I have purchased this from the home use program,

it IS legitimate.
