File is corrupt, bad, or missing
If the file or program you’re attempting to run is corrupt or missing, Windows will be unable to execute the file properly and sometimes generate this error message.
If you downloaded this file and verified it is complete and compatible with your version of Windows, delete the file and try downloading and running it again. It’s possible during the download that the file became corrupted.
Finally, if the second download does not work, try downloading the file from a different webpage. It is possible that the person or company maintaining the website mistakenly uploaded a corrupt version of the file you’re attempting download.
