I am attempting to use a code that allows me to generate data plots and automatically put them in a PowerPoint presentation. The function in the script that is giving me the most trouble is actxserver. Whenever I try to use it for a PowerPoint application, by typing actxserver('PowerPoint.Application'), it gives me an error that says "Server creation failed. Invalid ProgID 'PowerPoint.Application'". I have PowerPoint installed so I'm not quite sure what the reason for the error is. Any help would be greatly appreciated. Thank you!

Invalid ProgID 'PowerPoint.Application'

This would indicate that powerpoint is not installed properly.

I think it would be very unlikely that the progID for whichever version of powerpoint you've got installed is not PowerPoint.Application. You could check for sure by doing a search in the registry for Microsoft PowerPoint Application. One of the entries found should have a subkey with the name VersionIndependentProgID which will contain the registered ProgID for powerpoint.

As I said, the best place to find it is by searching for Microsoft PowerPoint Application. It will not be under HKCU or HKLM. On my machine it is under HKEY_CLASSES_ROOT\Wow6432Node\CSLID\{91493441-5A91-11CF-8700-00AA0060263B}

The node will depend on the bitness of your OS and of Office. The actual CLSID depends on the version of Office.

But as I said, it's unlikely that you got the wrong progid. I'd look into reinstalling powerpoint (or maybe try the office repair assistant).

Thanks again. I was able to find that location and under VersionIndependentProgID it does display PowerPoint.Application. I'll give the office repair assistant a shot as well as trying to reinstall it.
