AutoCAD .NET :: Creating Icon To Launch DLL

I have a .net program that I would like to run using an icon.  I've done this before and it worked, but now it's giving me an error.

I created the icon and command, I added the following to the command line:

^C^Cnetload "C://Program Files//my stuff//myProgram.dll” adp

(adp will lanch the program)

I get the following:

netload Assembly file name: "C://Program
Files//mystuff//myProgram.dll” adp

Cannot load assembly. Error details:

System.ArgumentException: Illegal characters in path.

at System.IO.Path.CheckInvalidPathChars(String path)
at System.IO.Path.Combine(String path1, String path2)
at ?A0xe1e1f031.NormalizeLoadFilename(String fname)
at Autodesk.AutoCAD.Runtime.ExtensionLoader.Load(String fileName)
at loadmgd()

Originally I tried using single slashes (/), but it still gives the same error.  It seems to have trouble with the spaces in the file path.  How do I work around that?
