Yes, cyber igor is using RC2.
In any case, that's how a C::B configuration export in RC2 did looked, an ini file.
Thanks for the clarification. I did not know
Anyway, if you want to use RC2, the easiest and safest way is to set the install path in the dialog that shows up when you first load the plugin. I don't remember how you call that dialog again later (it's like half a year since I last used that plugin), there is probably some small button somewhere in its main dialog.
If you want to use the HEAD version (or a nightly build), then change the xml file as described above, the respective config dialog got lost, as mentioned.
The forementioned "just place a config file on a CDROM" feature will obviously only work with a recent build (RC2 uses the registry to store settings, there's no way to make it "independent").
