..cause you just drag and drop the Hialgo & ENB zip files to RCRN to install it. However there is no way to tell if it is the InjectorVersion, WrapperVersion or both that gets installed from the ENB zip.

According to the installation instructions for ENBoost you need to install the WrapperVersion of ENB before installing ENBoost.

Does anyone know which RCRN installs? Also is ENBoost compatible with RCRN?

ENBoost should be compatible with RCRN but I wasn't able to figure it out either. This was more than a year ago and can't recall specifically what I got stuck on... probably something similar to yours. If someone can thoroughly explain what to do I'd appreciate it.
