If you are on windows running Ruby 1.8.4 it is because of a tab in the  
file. Downgrade to Ruby 1.8.2.

If you do this, you need to also force Instant Rails to update all of  
the  
paths. One way to do this is to rename the Instant Rails directory and  
then  
run Instant Rails. Then rename it back to the original (otherwise the  
start  
menu shortcuts from the one-click installation will point to the wrong  
place).

Download the setup file from rubyforge  
([http://rubyforge.org/frs/download.php/4174/ruby182-15.exe](http://rubyforge.org/frs/download.php/4174/ruby182-15.exe)). Run it,  
and choose InstantRails\ruby as the path. I think that should work.  
Try it and see.
