Having spent the last 5 hours trying to install PEAR I'm somewhat at a loss for what to try next. The initial go-pear.phar running from the command line produces the following error:

I can install the PEAR files from the package, but this doesn't include the pear.bat file and other registration files. I can't use the web installer because it puts the package manager in my www directory, and if I try moving the files the path variables all fail to work again. I've searched Google for ages and nowhere can you download the files on their own- everything is just circular references getting back to go-pear.phar, which does not work. I've tried using older PHP versions (5.2.9) without effect.
The system is running through EasyPHP on Windows 7 64 bit, account is a single account administrator, UAC is disabled. Can someone zip up the PEAR files and host them somewhere so that I can get hold of them to install manually, as this would be the quickest way to solve the issues?
