A week for installing CI on IIS?

Hi. it is the sixth day trying to get CI working under IIS 5.1! I searched the forums for everything related to IIS. the best result i ever had was that it remains working for a few hours!!! i wonder how can the runtime's behaviour changes without i touch it?

I doubted that Zend IDE was the reason, because it changes the format of the file to make it readable. I switched to notepad (please tell me a link to download the IDE used in the video tutorials), no change so far. i always have to restore the original files of the directory CodeIgniter... ok, the information in the routes.php was never effective, no default controller was ever loaded by visiting codeigniter/index.php
Nothing is effective when changing the config.php file.

I tried debugging the index.php file, stepped into each statement, change every / in path$ to \\ , and finally restored the original files. to get them working.. not working.. working ... not..

At the best condition i saw, however, refreshing the page comes with a deffirent result. the standard 404 after refresh brings the perfect method execution, the second refresh brings the 404 back, and so on.

I just decided both getting wamp and posting a new helpme. the site will be hosted on IIS. I read some deffirences when running the same CI app under Apache and IIS.
