Hyperlinks restrictions window now appearing in Word 2010

[gogreen]

When I Ctrl-Click a link (true hyperlinks) in a Word 2010 document, a window now appears telling me the operation is cancelled due to restrictions in effect on the computer. I've read this may have something to do with my uninstalling and reinstalling Firefox 56.0 (32-bit), which I did before the problem began.



I read that making Internet Explorer the default browser can solve the problem, but that didn't work. Ctrl-Click on Word links on my laptop works fine, so I also read that copying from my laptop (same windows and MS Office setup as my desktop) the register key HKEY_Local_Machine\Software\Classes\htmlfile\shell \open\command and pasting it into my desktop registry might work, but it didn't. I also tried removing the Ctrl part of clicking to follow hyperlinks, but that didn't solve the problem, either.

How can I get links to work again in Word 2010 documents on my desktop PC?
