When attempting to open a presentation in the Assette PPTX Editor, users may occasionally encounter a “Failed to open” error. This message indicates that the PPTX Editor was unable to launch or open the presentation file as expected. This article outlines the most common causes and offers guidance for resolving the issue. The full message reads: “Failed to open the powerpoint presentation. Please contact Assette Client Service for any assistance”

1. Check Internet Connectivity #
The Assette PPTX Editor requires an active internet connection to function correctly. If your computer is offline or experiencing network issues, the editor may be unable to launch.
- Ensure that your computer is connected to the internet.
- Open a web browser and verify that you can load external websites.
- If you are on a corporate network or VPN, confirm that the connection is stable and not blocking Assette services.
2. Close Any Crashed or Unresponsive PPTX Processes #
A previous instance of Microsoft PowerPoint or a crashed PPTX process may prevent the Assette PPTX Editor from opening a new file.
- Press
Ctrl + Shift + Esc
to open Task Manager. - Under the Processes tab, look for any instances of PowerPoint or files with a
.pptx
extension. - Select and end any instances that appear unresponsive or are no longer in use.
- After clearing the processes, attempt to reopen the Assette PPTX Editor.
3. Close Any Open Instances of the Same PPTX File #
If the same PPTX file is already open—either in the Assette PPTX Editor or Microsoft PowerPoint—or you may simply encounter the “Failed to open” message.
- Check if the file is already open in another PowerPoint window.
- Save and close the file, then try reopening it via the Assette PPTX Editor.
4. Rename One of the Files if Two PPTX Files Share the Same Name #
Microsoft Windows has a limitation where users cannot open two files with the same name, even if they are stored in different directories. If you already have a file open with the same name as the one you are trying to open, this may cause a failure.
- Close the unrelated file that shares the same name, or
- Rename one of the files to a unique name and try again.
5. Ensure You Are Using a Windows Operating System #
The Assette PPTX Editor is only supported on Windows operating systems. Attempting to launch the editor on macOS will result in a failure.
- Confirm that you are using Microsoft Windows.
- If you are on a Mac, use a Windows machine or virtual environment supported by your organization to open the PPTX.
6. Additional Considerations #
While the above reasons cover the most frequent causes, there may be other environment-specific issues that affect the PPTX Editor:
- Antivirus or endpoint protection software may block the editor’s launch. Check your security software logs or temporarily disable it to test.
- Corrupted PPTX files or files that failed to generate correctly in Assette may prevent opening. Re-download the file from Assette if possible.
- Office integration issues or an improperly installed version of Microsoft PowerPoint can also interfere. Ensure PowerPoint is properly installed and activated on your system.
If none of the above resolves the issue, contact your IT administrator or Assette support with relevant logs or error details.
