SE forum topics on SoA install issues are like digging for answers in a barrel of cotton wool.
A simple thing like download expansion click on install and ffxi not installed is thrown up. I have 3 computers and they all get the same remark ffxi not installed where I have been playing them for years. So the issue is with the software download either not being specific
for the region or more likely corrupt or not done right with bugs or all three. If SE cannot do this right what hope for the rest of us.
