<p>I am trying to learn some of the basic and advanced features of visual studio, Anyone find sites that have this type of information ?</p>

<p>I see this:</p>

<p><a href="https://stackoverflow.com/questions/86355/best-way-to-learn-visual-studio-power-features">https://stackoverflow.com/questions/86355/best-way-to-learn-visual-studio-power-features</a></p>

<p>But it seems more related to tips and advanced features.</p>

<p>All three versions ( 2003, 2005, 2008 ) </p>

In the command line window type
```
PATH
```
then hit return, do you see
```
ruby.exe
```
on the
```
PATH
```
environment variable?
If you installed ruby to say
```
c:\ruby
```
then it'll be
```
c:\ruby\bin\
```
.
Looks like it may be missing from the path.
