adobe digital editions

Adobe Digital Editions has not been able to load to my PC since my Windows 10 updates on 18 Feb 20.  I have a HP laptop that I bought with Windows 7 (worked fine); took the free upgrade to Windows 10 when Microsoft put it out (everything got real slow).  I've been using Adobe Digital Editions always with no trouble.  I don't have WiFi at home, I mostly read and watch DVDs on the PC.  The library has free WiFi, I use it for library Ebook loans, Project Gutenberg downloads, and updates.  On 18 Feb 20 I got some Gutenberg downloads, some library E loans, and updates.  When I got home the machine said it neede a restart to finish installing updates.  I restarted it, and Digital Editions has not come up since.  The short cut is there but it does not load. 

Since then I have re-downloaded from Adobe homepage, I've "reset" Windows; I have "fresh start" Windows; and the ADE still will not come up.  There is a miniature splash page but it just stops.  I use Task Manager to "end task" to get it off the screen.

There are other ebook readers but it seems I would have to load each book one at a time.  And the library wants Adobe Digital Editions to load their stuff.

I'm stuck.
