Adobe Reader no longer opens

I have Windows 10.  After a recent Windows update, Adobe Acrobat Reader DC will no longer open when I click on the icon, nor open when I right click and run as administrator.  If I click on a PDF file it will not open Reader either. 

I removed the Windows 10 update, and took my computer back to a restore point before Adobe Reader stopped working, but it still won't.

I tried using a Adobe Reader repair tool, rebooting, reinstalling Adobe Reader;  I tried simply uninstalling Adobe Reader myself and downloading it again and installing it, it still does not work.

I checked and Adobe Reader is the default app to open PDF files.

Under Windows Services, Adobe Acrobat Update Service is Running and set to Automatic.  So are Adobe Genuine Monitor Service and Adobe Genuine Software Integrity Service. There is also an Adobe LM Service listed as Manual Startup type.

Frustrated, I loaded a program called PDF Viewer Plus, and that works to open the PDF's.  So I know they are not corrupt.

But I would like to use Adobe Reader again.

No other program on my computer has ceased to function, only Adobe Reader.

Help!

    Thank you.  I had done most of what you suggested already.  I had not  created a test user profile, and it turns out I did not need to.

    The problem was not caused by a Windows update at all;  it was actually caused by my antivirus, Avast.  I discovered that I could tell Adobe Reader to run with protected mode turned off.  I researched that on the web and discovered many people had the same problem, with various antivirus programs.  The solution with Avast was to remove a registry key: go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options, then delete the key AcroRd32.exe

    Reader worked after that.

    My problem is similar AND recurring (like monthly!), with these differences:

    I'm using Windows 8.1, not Windows 10. And when Reader stops opening, I eventually, after about 5 minutes, get "Acrobat failed to connect to DDE Server". AND when I look in the folder to which I download programs, the Reader installation file readerdc_en_la_crd_install.exe is ALSO gone. It's gone now as I'm typing this, but Reader is functioning.

    I have written myself a reminder to see if this happens every time I do a Windows update.

    I thought at one time that the problem was caused by CCleaner's Registry Cleaner tool. But then I stopped letting if fix any problem it found that had "adobe" in it. That didn't stop the problem from recurring.

    So, every time this happens, I have to uninstall reader and download the installation file again, which on DSL at 4.7MPS, takes for effing EVER.

    Any new diagnoses since October, 2018?

    Thank you.
