Thank u guys for help , but i couldn't use that link u gave .. howeva ,, after near 3 or 4 days working with java script ( which i dunno nothing about ) , i've discovered the source of the problem ,, and it took me much long time to tweak the WPI .js files to work from anywhere ( from cd , network , local path ,, any thing ) ,,, and after i've finished the whole thing , i used some user's tweak to pass all variables of the system to the replpath script in generate.js ,, not only the ones specified there ... and after that long effort , and good customization of the WPI .js files ,, i would ask the WPI project manager to edit the .js files to help new beginners have a smooth , clear installation with no errors .. plz help beginners , plz edit the WPI and if no one is free for that , i could do it myself and hand u the edited files to publish them as a new build ...
