Artuclate Presenter 13 stopped working- Error message

Hi Kishore and welcome to the community!

Sorry to hear about the trouble you're having with this.

At what point do you see this error? Does it happen as soon as you launch Presenter/PowerPoint, or when you're trying to use the ribbon, insert media, etc.?

First, please make sure you're using a supported, 32-bit, installation of Office:

Articulate Support - Supported Versions of Microsoft Office

Please try the troubleshooting steps outlined in the following article:

The Articulate Tab on the PowerPoint Ribbon Is Missing

(This should also resolve an unresponsive Articulate Ribbon)

Also, please make sure that you're working with local project files:

• Work on your local drive (your C: drive). Working on a network drive or a USB drive can cause erratic behavior, including file corruption, loss of audio, and other unexpected behavior. 
• You should also make sure the directory path to your project files and your published output is less than 260 characters (for example C:\Articulate).
• Avoid using special characters, accents or symbols in your file names (this includes spaces and underscores).

Additional information regarding "Naming Files, Paths, and Namespaces" in Windows operating systems can be found in the following Microsoft article.

You mentioned you've already reinstalled. Which method did you use for this? If you haven't already, please try the steps outlined in this article:

Unexpected or Erratic Behavior in Articulate Studio

Let me know if you still see that error after trying all of those suggestions.

Thanks!

Christine
