Could not complete your request because there is not enough memory (RAM)

I succeded this way  ( Windows 10 pro 64 bits, 4 GB RAM, 2 GB video memory, 200 GB free space SSD / 500 GB, Intel dual core):

• I Pressed the Windows logo key and R key to open the Run dialog.
• I Typed regedit and pressed Enter.
• In the Registry Editor window,I navigated to HKEY_CURRENT_USER\Software\Adobe\Photoshop Elements\16.0 folder. With right click, I  created in this folder a  new key named  OverridePhysicalMemoryMB and pressed Enter.
• I clicked right on the newly created key and chose Modify.
• I Changed the Value Data from 0 to a numeric megabyte value that reflects a little bit less than my system's physical memory. For example, I entered  4000 for 4 GB, (instead of 4096) .
• In the Registry Editor window,I navigated to HKEY_CURRENT_USER\Software\Adobe\Photoshop Elements\14.0 folder. With right click, I  created in this folder a  new key named  OverridePhysicalMemoryMB and pressed Enter.
• I clicked right on the newly created key and chose Modify.

• I Changed the Value Data from 0 to a numeric megabyte value that reflects a little bit less than my system's physical memory. For example, I entered  4000 for 4 GB, (instead of 4096) .

photoshop elements does work normally

Also tried to download Elements 14 again to re-install and cannot find anywhere to do it. I am now stuck with no PSE and do not wish to be blackmailed into buying the newest version for $70!
