The MSN Explorer is not compatible with Windows 10. I've checked Microsoft, and it appears that the repair tool only works with Windows versions up to Windows 7. That's why it has errors on Windows 10. You will have to look for a replacement, or downgrade from Windows 10 to Windows 7. There is a feature called Go Back in Start > Settings > Update & Recovery > Recovery, which allows you to go back to previous version in a time frame between 1 and 30 days.
