I am trying to install Adobe Acrobat Standard DC 2015 release on my Win10 pro. I had to upgrade my motherboard, Ram and video card. Same processor Same OS. It ran on this OS before just fine. Also with an older motherboard and ram. Now it wont install. Says I need to update my OS and browser. It opened a dated browser and there is only 1 OS above the one I have. One of the "Adobe" chat room techs said that the program was to outdated to run on Win 10 Pro. Not true as it ran just fine on the very same OS before the "Upgrade". My thought is that I may be being forced to purchase a newer version when the one I have worked just fine. Any help would be greatly apprieated.
Hope you are doing well and sorry to hear that.
