I have downloaded the bindiff420-win-pluginsonly.zip file and unpacked it in a directory with plug-ins. After loading of IDA 6.9 I have noticed
error: Couldn't load configuration file, skipping BinDiff plugin.
What have I missed?
download bindiff-license-key.zip. Extract the contents to a file named BinDiff.xml and place this file in the same plugin folder.
