I had thought my problem was php_phar.dll was not loaded and when uncommented didn't even exist in ./ext/
So I grabbed the windows php zip for my version and noticed it wasn't in there either!
Well anyways not requiring the PHAR Hash did get it to install
EDIT
Turned out i had another error. I checked phpinfo() and pear include path was something weird like c:\php5\pear
Pear install
