Wonky Preview Window Behavior

[Magnus]

Open preview window. Select Excel xlsx file. All looks good.

Select PDF ... NET Error


Click through "continue" and then another popup window and the PDF appears in the preview.

Select the Excel file again. Image no longer looks like an Excel file, but just a smallish "table' excerpt.

Suggestions?

Are you using an Adobe PDF program? If so, this page has suggestions.

Thanks. I have NitroPro listed under the Office docs, but already have PDF-XChange on board, so I've followed the Adobe instructions.

Thank you.

If the problem persists: Are you using User-Defined Preview Handlers (Configuration | Preview | Previewed Formats | Categories)? That could explain a malformed GUID.
