I don’t understand why my computer won’t run any of my Ruby programs  
now. It keeps saying that they’re not valid applications… I’ve tried  
uninstalling and re-installing Ruby and restarting my computer, but it  
didn’t fix anything. Can anybody tell me what the problem could be…??  
They worked a few hours ago. ☹

Has something reset your path?

try this:

\<full\_path\_to\_ruby\>\ruby.exe \<script\_to\_run\>

of course replace \<full\_path\_to\_ruby\> with something like C:\ruby\bin  
(or  
wherever ruby lives) and replace \<script\_to\_run\> with the name of the  
ruby  
script.
