Some stupid website I use regularly forced me to "update" my Reader to Adobe Reader DC, but I have a fully licensed full version of Adobe Acrobat X Pro. Unfortunately, I cannot seem to find any place to reset my default for opening PDF files back to Adobe Acrobat X Pro. When I go into Windows 10 settings and select Pro as the default instead of Reader DC, it does not change the icon, nor does it change the default action. I cannot uninstall Adobe Acrobat Reader DC because of websites I use that require it (unless you know of some way to trick them into beliving X Pro is OK), but I can't stand having PDF's opened with the Reader by default, and then I can't do anything with them, so need to manually open them from within X Pro. Any ideas or solutions would be a HUGE help. Thanks in advance for any help!!
Adobe don't support mixed versions. You can upgrade to Acrobat Pro DC, perhaps.
Agreed, but they can't upgrade. There's no upgrade path from X to DC. They'll need to purchase a new license.
Maybe give this routine a try...
Without Reader or Acrobat open, locate a PDF file in a folder, and right-click on it. From the options presented, choose Open with, and jump down to the bottom where the Choose another app options sits.
Choose your Acrobat program, and be sure to select the 'Always use this app to open .pdf files' option.
Hopefully this will help.
