MIME Content Type: application
A particular section of the web content that you tried to browse was encrypted in the MIME Application/Powerpoint format. To properly render data embedded in this format, your PC requires either a particular browser plug-in or an application that is capable of decoding information according to the MIME Application/Powerpoint specification.
To learn more about MIME Application/Powerpoint, please refer to RFCs and the lists of related MIME types or File Extensions.
Web browsers, like IE and Firefox, use MIME Types to determine the best host applications to render and present binary data sets that are embedded in web pages. When you encounter a MIME Application/Powerpoint error, it is caused by one of the following two types of errors:
1) You PC doesn't have a host application that can open and render MIME Application/Powerpoint content. Like file extensions, each MIME Type corresponds to a particular host application that can be used to read and write binary data sets according to the matching MIME Type specification.
2) Your PC may have errors in the Windows Registry due to corrupt and invalid entries. Even if you have a matching host application installed, it couldn't be found and used by the Internet browser.
It is strongly recommended that you scan your PC to identify and correct these errors to properly view content embedded in MIME Application/Powerpoint format.
