[amelia] Amelia fails to install

AmeliaView 1.6.4 running on a Windows 7 64-bit system, produces "can not find script file "C:/Windows/system32/amelia.vbs". Trying again In R I get: Warning in install.packages("Amelia") : 'lib = "C:/Program Files/R/R-2.15.2/library"' is not writable Error in install.packages("Amelia") : unable to install packages = "source") Warning in install.packages("Amelia", repos = "http://cran.r-project.org", : 'lib = "C:/Program Files/R/R-2.15.2/library"' is not writable Error in install.packages("Amelia", repos = "http://cran.r-project.org", : unable to install packages Clearly something is wrong. Any suggestions?
