My desktop app keeps crashing. This keeps happening even after updating the app. If this keeps happening I will be forced to look for other apps to edit documents. I have Windows 10. I read that you are working on this issue back in May of this year. Is it resolved? https://community.adobe.com/t5/acrobat-discussions/error-message-quot-the-instruction-at-0x000000006605d107-referenced-memory-quot/td-p/14563550
