[BioC] problem upgrading limma on Windows Vista

Perhaps someone has seen this behavior and can help:

I am working with a student who has a Windows vista laptop.  She had 
installed R 2.6.2 and Bioconductor.  When working with the swirl sample 
data set and trying to normalize within arrays, an error with the lowess 
function was occurring.  I checked the limma version and it was 2.9.7, 
so we tried to install limma 2.12, but got a warning that the prior 
version of limma cannot be removed.  Oddly, the machine is in a state 
such that if from the R GUI we choose Packages->Load Package, limma does 
not appear on the list (which makes sense because there is no limma 
folder in C:\Program Files\R\R-2.6.2\library).  Yet if we try to install 
limma, we see the 'cannot remove prior version' error.  We even 
uninstalled R and re-installed it, but the same problem with installing 
limma persists.

I guess I never should have joked early on that we could probably blame 
this problem on Vista...but it's looking like that may be the case.  Any 
ideas would be appreciated.
