[Blind-sysadmins] Accessibility for Keri prox card system

Hello everyone: Currently at work we are using the keri prox card system to manage our employee proxs cards. The system is currently running on the windows server 2012 and I’m using NVDA as a screen reader. However, when I try to access the menues in this program the program closes. Also, I cannot OCR the screen with NVDA. It is telling me windows 10 OCR for NVDA is not available. Does anyone have experience with the system? If so, what are the accessibility recommendations? Regards, Kathryn
