I was able to pick up X4 Ultimate for 19.99 (if the mail in rebate ever arrives) and thought that would be well worth for the Mercalli and Boris effects.
I did not want to re-install X4 so I simply installed the 2 new items from the main menu of the DVD under "Bonus Contents"
I did this on 2 PC's but on the 2nd PC (my main one) the Boris installed fine but when selecting Mercalli it installs some sort of X4 update.
I guess I'll probably have to do the complete uninstall and then re-install but I would rather not as I have X4 setup just the way I like it with folder layout and items loaded where I like them.
Just curious if anyone had run into this.
