Hi marka25245057 ,
Please provide the exact dot version of the software & OS installed at your system .Also check whether is there any update available for the software after going through "help > check for updates "
Follow this thread to reset the preferences for the Acrobat software :- How to reset Preference settings in Acrobat.
Also after opening Acrobat, navigate to Help menu & repair the installation.
Try this :-
Open PDF in Acrobat
Go to File > Export To > Image > JPEG
From the Save As dialog click on Settings button at the bottom
From the Color Management pane
Click on the drop down for RGB
Select Off & Ok
Save the file as JPEG
If the issue still persist, please check with the different user account to replicate the issue.
Adobe Acrobat Pro DC Version 2015.006.30121
Win7 Professional 64 bit kept updated.
Are you suggesting I try to replicate the issue after each step, or is this a series of steps that must all be completed in order before I try again?
I went though each step. The last one worked (changing RGB from "embed profile" to "off"). Not sure why that worked, but it did. Thanks.
