    How do I open the .lrreg file to get my serial number for lightroom 5?

      After purchasing Lightroom 6 I found that I cannot locate my serial# for Lightroom 5 in order to activate it under the upgrade option.  It is not listed under my account as a registered program, although I did register it at one time.  In fact I updated LR 5 several times from 5.0 thru 5.7.  I read that you can find the serial # under Windows at c:/users/program date... etc.  I found the .lrreg file that supposedly contains the serial # but it cannot be opened.  Does anyone know how to open this file.  It seems to be specific to Lightroom.
