Install RoR on Vista problem

Hi
I have tried to install RoR on my Vista machine but with no success
yet.

First I followed the tutorial getting started at RoR website &
everything worked up to the home page not showing in
http://localhost:3000
browser.

The Windows error message is:
<<>>>localhost is not set up to establish aconnection on port
3000 with this computer

I tried an internet search for help on opening ports in Vista and have
not found any suitable help yet!
I also run Xampp & IIS on my Vista machine (Xampp uses Apache server &
MySQL) & these are working fine (I followed internet articles to set
up & install them).

As this didn’t work I have tried installing RoR with Cygwin from this
youtube presentation:

(Cygwin with sqlite3)

This gets as far as opening the default homepage in
http://localhost:3000
but this is not correctly installed & I have this error at ‘About your
applications environment’:

About your application’s environment
We’re sorry, but something went wrong.
We’ve been notified about this issue and we’ll take a look at it
shortly.

I have spent somewhile trying to fix this but without success.

Can anyone please offer a solution? I look forward to helpful replies,
many thanks

Hi
Well sadly I had no reply to my original post for help about my RoR
being rubyOFFrails so I am replying now to my own post to update it.
I have now found a solution - I was using Ruby19 and windows vista
baulked at this (at one stage saying it could not find
mscrvtruby18.dll (?)). So I looked harder at the RoR download page &
it recommends Ruby 1.8.7
I could not find this but I uninstalled Ruby19 & have installed Ruby
1.8.6 instead and then followed an installation tutorial at

http://www.wdvl.com/Authoring/ror/Vista/saurabh_bhatia10202009.html

(using sqlite3-ruby & mongrel) & I have now the home page up & running
on localhost:3000- problem sorted!

Now I look forward to following the further instructions & developing
with RoR.

Well it is good to talk-even if it is only to yourself!
Maybe this post here though may help others to set up
without Ruby19 which wasn’t compatible with Rails for me! Goodluck…
