Hi Deborah,
Upon looking up the error message, I found out that it has something to do with the Raptr app which is likely installed on your PC. If you try to search for more information about the Raptr app, you'll see that this app installs more than 300 files including pythoncom26.dll.
To rectify the issue, all you need to do is uninstall the app.
Please let me know how it goes.
