Application Install Failure

A little assistance needed. Using Package and Deployment...and receive an error during install.

The error I am receiving comes near the end of Installation and it references msftqws.pdw & dllSelfRegisterEx as the cause for the error. Both of which, I cannot find in my app. Any ideas?

The exact error is "The file 'C:\DOCUME~1\IBM\LOCALS~1\Temp\msftqws.pdw\$(DLLSelfRegisterEx)' could not be registered because it was not found."
