You can put a trace on normalizePath to get the name of the offending
input file name.  E.g.,

   > trace(normalizePath, Quote(cat("normalizePath: path=", path,
"\n")))
   Tracing function "normalizePath" in package "utils"
   [1] "normalizePath"
   > install.packages("sn")
   trying URL
'http://cran.fhcrc.org/bin/windows/contrib/2.8/sn_0.4-10.zip'
   Content type 'application/zip' length 320643 bytes (313 Kb)
   opened URL
   downloaded 313 Kb

   Tracing normalizePath(lib) on entry 
   normalizePath: path= E:/PROGRA~1/R/R-28~1.1/library 
   package 'sn' successfully unpacked and MD5 sums checked
   Tracing normalizePath(tmpd) on entry 
   normalizePath: path=
C:\DOCUME~1\wdunlap\LOCALS~1\Temp\Rtmp2XNJo1/downloaded_packages 

   The downloaded packages are in
           C:\Documents and Settings\wdunlap\Local
Settings\Temp\Rtmp2XNJo1\downloaded_packages
   updating HTML package descriptions

It looks like your second call to normalizePath caused the problem.
If the error message from normalizePath included the offending file
name it would be easier to track down the problem.  E.g.,
   > normalizePath(c(".", "no such file.txt"))
   Error in normalizePath(path) :
     path[2]="no such file.txt": The system cannot find the file
specified
instead of just
   > normalizePath(c(".", "no such file.txt"))
   Error in normalizePath(path) :
     path[2]: The system cannot find the file specified

The following, barely tested, patch does this on Windows.  I don't
know if
   ...[printf]... "%ls", filenameToWchar(string,FALSE)
is the proper way to display an R string.

It might be nice to include the current directory also.
