I do have the same problem. Installing Coldfusion MX7 under Windows XP f... up Apache (version 2.2.0: is this a "apachefriends" nomenclature? Can't seem to find this version anywhere else ...).
The startup log says: "apache.exe: Syntax error on line 534 of C:/Programme/xampp/apache/conf/httpd.conf: Cannot load C:/CFusionMX7/runtime/lib/wsconfig/1/mod_jrun20.so into server: Die angegebene Prozedur wurde nicht gefunden."
Don't miss me: the path is correct; the file exists. From hearsay I take it that CF developers relied on some Apache 1.3 compatibility stuff that no longer exists in Apache versions 2.0 or more recent.
If you happened to find a solution to the problem let me on to it sending a private message. I'll do the same.
