Error loading "oligo" Bioconductor package - r

Question

On Windows XP, After updating to R 2.15.3 and updating all libraries, I was no longer able to load the "oligo" package from BioConductor.
To recreate:
source("http://bioconductor.org/biocLite.R") #install the BioC installer
biocLite("oligo") #download and install the oligo package
library("oligo") #attempt to load
Gets the following error:
Error in inDL(x, as.logical(local), as.logical(now), ...) :
unable to load shared object 'C:/Program Files/R/R-2.15.3/library/affxparser/libs/i386/affxparser.dll':
LoadLibrary failure: The specified procedure could not be found.
The file it mentions, "C:/Program Files/R/R-2.15.3/library/affxparser/libs/i386/affxparser.dll", is right where it's supposed to be.
