We ned to execute a custome exe from within IE on our Intranet.  I'm working with the sampke code from http://support.microsoft.com/?id=232077
The program is not digitally signed yet, but will be if we can provve that the method will work for us.
I place this html file and the program MyProgram.exe in two folders.  It works if it is in
C:\MyTest
But not if it is in.
C:\Program Files\Microsoft Visual Studio 8\VC#\CSharpProjects\MyProject
We need it to work no matter where it sits.
The script generates exactly the same code for the Iframe in either folder.
Any idea what I'm missing here?

Thanks

<p>This link requires that we Sign the exe.  Without signing you will get the yellow warning bar at the top of the browser window.  Click on the yellow warning bar and click Allow to test this code.  If we can sign the exe this code should work for us without the warning.</p>

I would check the folder permissions.  I believe that the "Program Files" folder usually has more restrictions by default, than other normal folders on the hard drive.

Please also try incorporating the escape() JavaScript function to the filename variable:

runnerwin.document.write(strpagestart + ecape(filename) +  strpageend);

This will encode it to be URL-friendly in case your file path translates to something else because of all the special characters.

Thanks.  It is, of course, a permissions issue.  We've moved it and it works well.  Now need to reasearch digitall signing the exe.
