Keycode assembly (Licensing.KeycodeDecoder.dll) cannot be loaded


I apologize if this has been posted about before here but in searching I can't find a reference to his with my exact same circumstances. I've seen posts regarding this for ASP sites and JAVA applications but not one specifically pertaining to a WinForms application.

I'm deploying a VS2010 WinForms application using CRVS2010 to a clean virtual 32-bit WinXP SP3 machine. I've installed the 32 bit CR runtime (CRRuntime_32bit_13_0.msi) along with my application, but previewing the report still generates an unhandled exception with the following entry from Crystal Reports in the Windows Application Event Log:

The description for Event ID ( 4353 ) in Source ( Crystal Reports ) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer. You may be able to use the /AUXSOURCE= flag to retrieve this description; see Help and Support for details. The following information is part of the event: The keycode assembly, BusinessObjects.Licensing.KeycodeDecoder.dll, cannot be loaded.

These same reports all run fine under the VS2010 IDE on my development machine. Is this a known error in the CR runtime and WinForms or have I missed something in the deployment process?
