Not enough memory space [hard drive]

If your computer doesn't meet the minimum requirements to run the latest operating system (Windows 10) + Creative Cloud + Lightroom + Camera Raw + Bridge + all other apps you intend to use, there's no hope for other software either.

You need a bigger, faster computer.  Or you could possibly postpone that purchase by uninstalling all non-essential software and move data files to external drives.  

=======

Beware of fake Adobe reps offering to sell you software or gain remote access to your computer.  It's a scam!  Run away!

>Windows 7 that I just updated to windows 4

That does not make any sense... you don't go from 7 to 4

If you don't have space on your hard drive, move data files to an external drive or delete unneeded files
