I found the Rgui.exe under directory R\R-2.12.0\bin\i386.
 
Thanks,

Generally packages do need to be rebuilt for new versions of R (other
than patch releases, where only the last digit changes).  R 2.12.0
supports both 32 bit and 64 bit Windows in the same installation, and
since Windows doesn't have MacOS-like "universal" binaries, that means
binaries need to be put in the right place.  Generally that's an i386
subdirectory for 32 bit, and an x64 directory for 64 bit.

I don't know why a 32 bit DLL wouldn't work with 32 bit R 2.12.0, but if
it was installed for 2.11.1, it might not be in the right place.
