Microsoft tech says it's an Adobe problem. Is a compatible version in the works? Is there a workaround. I tried uninstall/reinstall but the installer throws an error. The program installed anyway but still doesn't function. I've tried version 3 and version 4. I have the same problem on a machine upgraded from Windows 8.1 to 10 and on one updated from 7 to 10.
Is there any hope I'll be able to get back into my ebooks? Does anyone know of an alternate program?
