[Fix] Microsoft Outlook Cannot Preview PDF Attachments

Last Updated on: May 8, 2022 by Ramesh

Microsoft Outlook has attachment preview support wherein you can preview the file attachments without having to open the respective program. For this, Outlook utilizes the existing preview handler modules added by individual programs.

This article describes the various type of PDF attachment preview issues that users face in Microsoft Outlook/Outlook 365, and outlines the fixes for each type of issue.

Editor’s note: The PDF preview issues are usually caused if the installed Office/Outlook version is 32-bit, but your PDF reader is 64-bit. This issue seems to arise with a recent update of your PDF reader application (e.g., Acrobat Reader DC) from 32-bit to 64-bit. In this article, let’s see every typical PDF preview issue users face.Read more

[Fix] Error “Windows Photo Viewer can’t display this picture”

Last Updated on: January 10, 2022 by Ramesh

When you try to preview an image file (JPEG/PNG) using Windows Photo Viewer, the preview would be blank and the following error message is displayed:

Windows Photo Viewer can't display this picture because there might not be enough memory available on your computer. Close some programs that you aren't using or free some hard disk space (if it's almost full), and then try again.

It’s a misleading error message, as in most cases, it may not have anything to do with the system memory. The Windows Photo Viewer error is caused due to color profile metadata (ICC_Profile) embedded into the JPG image(s).

(You can reproduce the issue by transferring images from your Android/iOS mobile and previewing the image using Windows Photo Viewer on your computer. Another possibility is that your system has multiple video cards and the issue happens on the secondary graphics card only. Switching over to the primary video card may resolve the error.)

However, other utilities like IrfanView, GIMP, or the built-in/modern Photos app would be able to open the image correctly. This issue is limited to Windows Photo Viewer (and perhaps Windows Live Photo Gallery) only.Read more
