Since I installed Adobe Acrobat Pro DC, it causes my Microsoft Word to crash nearly every time I open it. I tried to remove the Adobe add-ons to Word, and that helped the situation, but they always come back, and then my Word (Windows 7) starts crashing again. Sometimes on a subsequent startup it works again, then crashes again. I have seen this problem addressed in the last three years in various forums and I expected updates from both companies to resolve this issue, but it has not. What's the problem?
