Pasting TRGSSX.dll

I must be misunderstanding something. I have copied TRGSSX.dll from the "Factory" demo. I went into my projects folder, opened the zip file containing my project, and pasted it in there. When I ran the Playtest, the playtest auto-closes. Going back to the zip file, TRGSSX.dll is gone. I have done this a few times.

I have also tried extracting everything and pasting it into the extracted file folder and then launching from that instance of the project. That tells me "Failed to create process" when I try and play test. What am I doing wrong? Do I need to re-zip the file after adding TRGSSX.dll?

EDIT: I should add that it is the first requirement, KGC Bitmap extension, which is causing the problem. I have copied over all other basic files as well.

Extract them, don't open them via zip file.

Looks like I got it figured out. I was placing it in the wrong folder. Rather than placing it in the source file in My Documents (a save area I didn't know existed) I was trying to place it in the Steam save within the Program Files folder.

That is, I should have saved it to "users/dean/documents/rpgvxace/project_folder"

when I was trying to save it to "program_files/steam/steam/steam_apps/common/rpgvxace/project_folder"
