Solution
I had the same problem while I was installing new Magento 2.0, after different hit and trials, I manged to solve it by following these steps:
I copied all icu* files from php directory to Appache directory, and it worked.
Php direcotry:
WAMP\bin\php\php5.5.12
Appache Directory:
WAMP\bin\apache\apache2.4.9
Make sure to un-comment following line in php.ini file:
extension=ext/php_intl.dll
