I'm in a localhost Windows environment, running PHP 5.4. I've been through the docs, and as far as I know all of the required modules are installed and enabled. PHP is in my PATH, and GPM is running commands, it just can't download plugins/updates.
Example: When running bin/gpm selfupgrade -f -v, after saying yes, I want to upgrade now, the response is
PHP
Preparing to upgrade to v0.9.43..
|- Downloading upgrade [2.31M].. 0%
[RuntimeException]

Any thoughts on what could be causing this?
