I have, yes. The only relevant statement I can find says BC3K - Legacy doesn't run under WinXP. In fact, it does, and others appear to have gotten it to run as well, based on other messages in this forum.
So, yes, BC3K under WinXP is an unsupported configuration. But heck, the whole GAME is unsupported -- in any configuration -- so I thought I'd see if anyone else had experienced and resolved this problem.
