gw2 Launcher Crash on install of addon-loader.

[Malfunciton]

When I install this either manually or via the addon manager it is preventing the gw2 launcher from opening and it Crashes. This occurs even if I delete any actual addons which makes me believe something is going wrong with this not the actual addin. I looked around in the registry as per another posts advice but couldnt find windows blocking it anywhere but I am fairly noob so not sure I was looking in the correct place.
