Recently, I decided to try and install Unity3D on my Linux box. I read here that I would need to use POL. So, I installed, followed all the instructions, and the installer started off.After a while, it started trying to download http://download.microsoft.com/download/d/3/0/d30e32d8-418a-469d-b600-f32ce3edf42d/WindowsXP-KB936929-SP3-x86-ENU.exe . It couldn't, the file was 0MB and POL just hung. (I'm pretty sure this is because it's past April 2014 and Microsoft doesn't host XP updates anymore). I had a read through the script I ran and I don't see anything about changing the version to XP, so I'm a bit stuck. If there was some way I could make POL stop trying to download this or download the update from somewhere else, that would be great.
