Problems updating Lightroom 6.01?

I have Lightroom 6.01 on my Windows PC, and want to update to 6.1.1.  When I go into "Help" and "Updates", it doesn't give me Lightroom 6.1.1 as an option.  Instead, it tells me there is an update to Lightroom CC 2015, which isn't what I want.  I did try clicking that to see if it would give me 6.1.1 anyway, but all I got was an error message saying "Update failed.  Download error.  Press Retry to try again or contact customer support (49)."  I pressed Retry and got the same result. I contacted customer support and they referred me to this forum.  Can anyone tell me how to get 6.1.1?
