This has to do with Tinn-R trying to write to etc\Rpforile.site, but you need
administrator rights  under Vista to do this. Tinn-R does not report an error
during the install phase when the write is not successful.

Workaround (alternative) :

-- Add the trPaths manually. In my system, it looks like:

.trPaths <- paste(paste(Sys.getenv('APPDATA'), '\\Tinn-R\\tmp\\', sep=''), 
  c('', 'search.txt', 'objects.txt', 'file.r', 'selection.r', 'block.r', 
'lines.r'), sep='')

-- Make the etc directory writable by adding your user account and write
