I have the same problem as Predatoria, but I just put VictoryPlugin folder in My_Project_name\Plugins folder as usual, and I have the same error, “Missing or incompatible modules in VictoryBPLibrary plugin - would you like to disable it? You will no linger be able to open any assets created using it”.
