I use adobe reader VI. Before installation of 10 I could edit all my files. Now I can't edit anything that has to do with abode.This happened immediately after the download. I did not change anything, Windows 10 changed it somehow. Not just the icon. I am familiar with pdf files. The file type did change to something that can not be edited, before it could. Now when I download a file it immediately become unusable, there are no fillable fields available. I have carbonite and they may be able to help but it seems that adobe is no longer permitted to make usable files for any of us due to Windows 10. I know Adobe sells programs that will translate them back to something useable for a monthly fee. I still haven't tried to open any of my business contracts that have writable fields on this computer. . Again, thank you all for your time.
