I had a client where Adobe Acrobat XI Standard, on Windows 10, worked flawlessly for several years, but recently documents would open and then after a couple of seconds close with no warning.  Reinstallation and reactivating did not solve the problem nor did many Internet search results such as registry edits.

What did work was to open Adobe and very quickly, before it closed, click  “Help” on the menu bar and then select “Check for updates”.  It did find an update, download, and install.  It worked fine after that.  I suspect a compatibility issue with a recent Windows update may have caused the problem.
