You should be able to choose KDiff3 in the dropdown. Normally you are not required to configure AnkhSVN to use KDiff3 manually. However it seems that automatic detection of whether KDiff3 is installed is broken in AnkhSVN. Tried with

我可以通过单击 ... 并用完整的宏 "$(ProgramFiles)\KDiff3.exe" 替换路径来解决这个问题文件系统上 KDiff3.exe 可执行文件的路径.
