Cancellation of Installation leads to unremovable(?) allocated disk space

The yellow space is what I suspect to be the allocated space.

Hello,

I have PoE installed on my D drive and not my C drive.

So today I launched PoE using the x64 .exe and I ran it as an administrator (I thought it would give me better performance). When it opened it went through what you would see when there is an update:
-Checking resources, allocating space, downloading

At first I thought there might have been an update, but when I saw it downloading 22GB, I figured something was off. So I cancelled the download and checked my disk.

Turns out, it had begun downloading another Path of Exile application on my computer in the C drive. I deleted what files were associated to PoE on the C drive, emptied the recycling bin, but it still says I lost around 20GB of space on my C drive. I'm assuming this is the allocated space.

I've even uninstalled PoE via control panel hoping it would take whatever it's allocated in the C drive with it, but it's only uninstalled the game from my D drive.

Does anyone know how to remove the allocated space? As it stands right now, I do not have enough space in my C drive to download PoE on it because of this so I can't just have it fully download.

Thanks.

Nevermind, solved. It was in the System32 folder. Just had to go there and delete it.
