PPTX Troubleshooting

Common Problems Opening PPTX Files

Apache OpenOffice Disappeared

Double-clicking your PPTX file prompts the message "%%os%% Can't Open PPTX File". If this is the case, it's usually due to the fact that you do not have Apache OpenOffice for %%os%% installed on your computer. This will prevent you from double-clicking to open the PPTX file because the OS doesn’t know how to handle it.

Tip: If you have another software that you know opens PPTX files, you can select it by hitting the "Show Apps" button.

Incorrect Apache OpenOffice Version

Occasionally, you might have an outdated version of Apache OpenOffice installed that's incompatible with your PowerPoint Open XML Presentation type. If you've got the wrong version of Apache OpenOffice installed, you'll need to install the correct version. The primary cause of this problem is that your PowerPoint Open XML Presentation file was created by a different (newer) version of Apache OpenOffice than what's installed.

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

Regardless, most of the PPTX file opening problems relate to not having the right version of Apache OpenOffice installed.

Other Causes of PPTX File Opening Problems

Errors opening PowerPoint Open XML Presentation files can still occur even with the latest Apache OpenOffice software installed on your computer. If you are still having problems opening PPTX files, there may be other issues that are preventing you from opening these files. Issues that aren't software-related:

• Windows Registry PPTX file paths that are incorrect
• The PPTX file description within the Windows Registry was removed
• Partial installation of Apache OpenOffice that did not fully complete
• File corruption affecting your PPTX file
• Your PPTX is infected with malware
• Drivers associated with PPTX software need to be updated
• Windows has inadequate resources to open your PowerPoint Open XML Presentation file
