I can no longer see pdf-files in the viewer. I just get scrambled text. I just updated my PDF software to Foxit 12. It was working in the earlier version.
I have clicked default in the ActiveX+Preview+Office+Web and I saw that as a suggested solution on your forum. No change. I also unclicked the Foxit boxes but no change.
Does it work in Explorer?
Yes works in Explorer
I use Opus 12.21 x64
12.21 is a year old now. Please try with the current version first.
If FoxIt still doesn't work in the viewer pane, please try these suggestions:
