Actually I have two problems, but am sure they are related to the same issue. If I start the command prompt by clicking on "start command prompt with Ruby", then Ruby commands are available; i.e., I can type "ruby helloworld.rb" (where helloworld.rb is a file I have created) and it will execute the code. However, if I go to the command prompt using start menu and typing "cmd", it does not respond to "irb", "ruby -v", "ruby helloworld.rb", etc. The attached screenshot shows the problem, with top left showing the cmd prompt with Ruby, and the bottom left showing the normal cmd prompt (giving the error "ruby is not recognized as an internal or external command, operable program or batch file"). I reinstalled twice, making sure I check the 3 check boxes during installation, but still have the same problem. Additionally, if I use SciTE to try to run a program called "helloworld.rb", it gives me the error "the system cannot find the file specified". Again, shown on the screenshot, right side. Any suggestions? Much appreciate the help. Attachments: http://www.ruby-forum.com/attachment/6834/cmdError.jpg -- Posted via http://www.ruby-forum.com/.
