If you're looking for answers, don't look here. I'll post a solution when I find it.
How did I get here?
First, I popped on over to the wee Irish fellow's site because I remembered seeing a link there. Downloaded the file (lotus_domino85FP1_w32_CZ344EN.exe), downed the server. Got the message above.
So I thought I'd jump over to Fix Central. Noticed that the file there had a different name (DominoServer_85FP1_W32.exe), however, same problem.
Anyone got a solution?
