HPL installation problem

[Rasuization]

I have a 64-bit HP laptop and downloaded Amnesia from Gamestop's App. I then downloaded HPL Editor suite, and followed the instructions. But, it did not work, and won't show up on the launcher screen when I try to use the level editor.

My dad, who is an IT, told me that it was because the download instructions were for a 32-bit computer. There are no other instructions how to install the programs into amnesia from it's main wiki site though, and I can't find any other instructions. How would I get the editor suite into Amnesia?
