Two PDF viewers

[Fernando]

I have two different programs for dealing with pdf files: Adobe Acrobat Prof 11 and Nuance PDF Viewer Plus. Ultra Recall used to show, in its internal browser, the pdf files with Acrobat; now uses pdf viewer. I do not know why, and I cannot change the parameters to come back to Acrobat, either in Windows 7 (64) or in UR 5.1. Any ideas?

It's not a UR question -- you need to configure Windows and those apps to use the desired app as the PDF viewer in Internet Explorer.

Try reinstalling/repairing the Acrobat installation.
