Troubleshooting Problems Opening PJPEG Files

Troubles Opening PJPEG Files

Adobe Photoshop Disappeared

When you double-click your PJPEG file, you may see a dialog box from your operating system stating that it "Cannot Open This File Type". Usually, this is because you do not have Adobe Photoshop for %%os%% installed. This will prevent you from double-clicking to open the PJPEG file because the OS doesn’t know how to handle it.

Tip: If you know of another program that can open your PJPEG file, you can try opening it by selecting the application from the programs listed.

Adobe Photoshop is Out-of-Date

Occasionally, you might have an outdated version of Adobe Photoshop installed that's incompatible with your Progressive JPEG Image type. Installing the latest version of Adobe Photoshop from Adobe Systems Incorporated is recommended. The primary cause of this problem is that your Progressive JPEG Image file was created by a different (newer) version of Adobe Photoshop than what's installed.

Tip: Investigate your PJPEG file by right-clicking and selecting "Properties" to find clues on what version you need.

Regardless, most of the PJPEG file opening problems relate to not having the right version of Adobe Photoshop installed.
