Installer always asks to install Rtools if include_Rtools=TRUE

Hi Jon, hope you're doing well.

So, I included Rtools in my installation, and the installer always seems to ask me to install it, even though I already have it installed, with the same version. I checked the regpaths.json file, and found no registry entry for the Rtools path, so maybe there's something to do with that.

I don't think the installer is checking to see if there's already a Rtools installation, I think it's simply running the installer by default. I am doing something wrong?
