Questions regarding installation of EB 1.1 and fixes

[bovi]

Installing under Program files is not a problem with XP.

Retroactive

Adjective
retroactive (comparative more retroactive, superlative most retroactive)

1. extending in scope, effect, application or influence to a prior time or to prior conditions

Basically, in this case it means it has effect on ongoing campaigns, as opposed to new campaigns started after installing the fix.

So as the interloper fix is not retroactive, it will not affect your current campaigns but only new ones.

Edit: I've put the explanation in the fixes first post, as you failed to see that in the post further down.
