IDCS5 Win X64

I am compiling my first CS5 plugin (this is a CS4 project upgrade) and am receiving some errors/warnings that I cannot seem to resolve.  Here they are:

Could Not Find C:\Program Files\Adobe\Adobe InDesign CS5 Debug\Plug-Ins\(WPCPrintDebug Resources)\*.idrc

I checked the Pre-Link Event command line, and it looked almost exactly that found in the porting guide on page 13; the only difference was "&del" instead of "& del."  Just to be sure, I changed the line to exactly match the guide, reran the compile, but that did not fix the problem.

BTW, the directory does exist, but it is empty.

..\objD\WPCPrintUI\PlugInStatics.obj : fatal error LNK1112: module machine type 'x64' conflicts with target machine type 'X86'

I've looked all over the project for anything that even remotely looks like an X64 checkbox and haven't found any.  I went into the VCPROJ file, found several references to x64 and removed the whole XML tag.  That doesn't seem to have hurt the project any, but I still get these errors.  What is an IDRC file and how do I generate it? 

And how do I turn off X64 in my project?

(For those of you who wish to gently chastise me for removing X64 specifications from the project, please remember that x64 is only valid for InDesign Server and we do not use InDesign Server and have no plans for using it in the future.)
