Photoshop CS5 constantly crashes on WIndows 10

Help!  I've been running Photoshop CS5 on Windows 10 for over a year without any issues until recently.  Photoshop will open for a second and then immediately close with no visable error message.  If I hold down Shift-Alt-Ctrl and delete the preferences file I can usually get it to stay open for a little while, but when I try to open a .psd it immediately closes.  I've uninstalled and reinstalled with no luck.

The event log always point to nttdl.dll as the culprit, so I;ve run the SFC and although it did replace some files, I still have the same issue.  I've pasted the event error log below, please help me get this up and running so I can process my Christmas card in time.
