If you are running Windows 2003, you may get the above message when trying to launch the installer. It will also specify that "WinVerifyTrust() failed with 80096004". This is caused by the lack of support for SHA2 hash algorithm used in the digital signature of the installer package.
The fix is to install a hotfix that adds SHA2 support -
This issue is specific to Windows 2003 only! If you are getting this message in other circumstances, then the installation package may in fact be corrupted.
