Camera Raw 8.7.1 is NOT used to update Lightroom. You have to update to Lightroom 5.7.1 to import photos from the Sony a7ii. If you do not have Version 5 than you will have to use DNG Converter 8.7.1 to convert your files for use in an earlier version of Lightroom.
Have latest update of LR
Please tell us the version number

Downloaded and installed Camera Raw 8.7.1 and restarted.
As Bob Somrak said, this won't help, and he provides details on what to do.
First time for doing this, i am trying to sitch photos from light room 5 to CS5, but light room keeps telling to up date camera raw plug in to version 8.7.1 which i have do twice, and still every time i tried to send photos to CS5 light room keeps telling me to down load camera raw file ver 8.7.1, any ideas?
Photoshop CS5 cannot use that version of camera raw. The most current version that it can use.is camera raw 6.7. You need to download and use the DNG converter to create DNG copies that will work with Photoshop CS5.
