HoloPatcher is stuck "Loading [Settings] section from ini..."

Howdy! Apologies if this is an issue that someone has already seen and fixed, but I haven't been able to find anything about it online and it's my first time using HoloPatcher. I'm trying to install a mod for TSL (leilukin's Handmaiden and Female Exile one). I've unzipped the mod, opened up the installer, and set the start and end points, but when I hit install it just gives me the message pictured and sits there. The install button becomes pressable again, but it doesn't do anything further. The mod's description does show up before I hit install, so I'm fairly certain I have the directories set up properly. I tried leaving it overnight, in case it was just taking a while, but there was no change. I didn't manage to find any mention of this issue on the mod's Nexus page itself, and I didn't want to bother the author, since they seem to be exasperated with the number of people asking about other issues. If anyone knows what's going on with the installer that would be a great help, but if not I'd take any advice on installing it manually. I've done that before; I'm just not sure how to go about it with this specific mod.
