Composer wont update to lastest package - cakephp

Question

I'm using Cakephp and Miles's uploader plugin. I've got the composer plugin installed, and I'm using the latest copy of wamp. Fileinfo extension is enabled in php. when I try to update using composer it doesn't - it just uses a previous version. If I change the json file to force an update to the latest version I get and error message telling me the ext-fileinfo is not present - but it is.............
I need to get the lastest version as I have an error which shows up on my webserver which is running php 5.3 (wamp is using 5.4)
Additional info:-
The main composer.json is :-
{"config":{"vendor-dir":"Vendor"},
"require": {
"mjohnson/uploader": "4.3.*",
"mjohnson/utility": "1.5.*",
"mjohnson/decoda": "*",
"titon/utility": "*",
"cakephp/debug_kit": "2.2.*"
}
}
I'm expecting mjohnson/uploader to update (
a sub set composer.JSON is held in the uploader package :-
{
"name": "mjohnson/uploader",
"type": "cakephp-plugin",
"description": "File uploader and validation plugin for CakePHP.",
"keywords": ["cakephp", "uploader", "plugin", "file", "validation", "attachment"],
"homepage": "http://milesj.me/code/cakephp/uploader",
"license": "MIT",
"authors": [
{
"name": "Miles Johnson",
"homepage": "http://milesj.me"
}
],
"require": {
"php": ">=5.3.3",
"ext-curl": "*",
"ext-mbstring": "*",
"composer/installers": "*",`enter code here`
"mjohnson/transit": ">=1.4"
},
"support": {
"source": "https://github.com/milesj/Uploader"
}
}
and I would also have expected mjohnson/transit to have updated

I had a similar problem with ext-fileinfo and ext-curl on Windows 7. My problem was the path variable causing the wrong php.exe to be executed by composer. If php -m from the command line shows ext-fileinfo is not present that could be your problem too.
