Launching executables from within PowerPoint 2007

Hi,

I am running Office 2007 on Windows 7. From within a PowerPoint 2007
presentation I am calling an executable (.EXE) to do something, and then
return to the PowerPoint slide. The EXE file is entered into the PowerPoint
2007 slide as an object and this object is activated by the "Activate
Contents" option (PowerPoint animation option).

However, Windows 7 security presents a warning message with a dialog. See
attached image for an example of what it look like when I try to run an
executable from within PowerPoint 2007. This warning message is generated by
the packager.dll file. See http://www.win7dll.info/packager_dll.html

The warning message is: The package you are about to open will run a program
contained in the package. That program could do anything! It may harm your
computer! Unless you are absolutely certain about the nature, source, and
contents of this package, please press the Cancel button.

So, perhaps you can help me with advice on how to properly run executable
from within PowerPoint 2007 without the warning message.

Thanks.
