I downloaded the Trygames version about one year ago, but never really thought about the fact that it did not show of in ad/remove software. The other day, I bought warlords. It won't install because no previous version of Civilization can be found. Is this a Trygames thing, with a reasonable workaround? I've looked all over for a way to fix this; you can bet that, if it does not work, I've tried it.
