I've seen others reporting this problem here, but I need more help as I've delved into this in great depth and tried absolutely any possible idea suggested.
It seems that a recent Windows 10 update broke the Acrobat PDF (I am using Acrobat DC) file association and insists on associating PDFs with the Edge browser. I open and work with PDFs all day long in my page layout business and must open them in Acrobat, not Edge. I've changed the file association back to Acrobat in all ways possible (there are many ways to do it in Win 10) and no matter what, it keeps going back to Edge. I have even disabled Edge (through instructions found on the web). Then the PDFs can't open in it, but Windows still re-associates them with Edge and then they don't open at all.
Most of the time when I open Acrobat I get the warning prompt box asking if I want Acrobat to be the default for PDFs and of course I click yes. I am afraid to click on the "don't show this again" box as I'm afraid that if I do that Windows will again associate the PDFs with Edge and I won't be able to tell Acrobat to be the default again.
I have set file associations for PDF to Acrobat via all of the different places in Windows settings and it constantly goes back to Edge. There doesn't seem any way to fix it on the Windows end of things (hopefully there will be another update that will fix it but I can't wait for that).
I am wondering if perhaps there is a solution from the Adobe end of things where it will lock Acrobat and not allow another program to take over the PDF file association. Is there any way do that? Or does anyone have any other idea (I'm fine with editing the registry if that will do it) to solve this? I am going crazy with this.
