My installed mods are:
Nodes as Tabs, Seperate Sticky & Normal Threads, TaigaChat, XenPorta and Herocraft Minecraft status.
As a side note, I've tried to install Vault(older version) wiki a few weeks ago and it failed also at the installer (uninstalled it afterwards via Addons -> Uninstall), maybe it didn't delete everything or whatever and causes now trouble?
