RAW files not downloading into LR - code 37

I just tried to download RAW files into LR, (I do this nearly everyday with no issues) and even though I can see the photos are  loaded, they are not importing. I am getting an error code 37—"Some import operations were not performed."

'The following files were not imported because they could not be read.' (37)

Reading through the error code list, bottom line it tells me: "Download a fresh copy of the installer from Adobe."

Can someone please direct me to where this can be downloaded from?

Thank you.
