Edit: yeah, looks like I just didn't know how to run a .bat file. I'm fine deleting this post if someone can tell me where/how to do that.
I'm new to this, so there's a decent chance I just don't understand what's going on, but instruction (1) is confusing me.
I've got all the files downloaded, but I don't know if I'm supposed to be running that fptw64 application first and then the .bat file or what.
Also, when I run the fptw64 application, it opens the cmd window and just has a list of functions, with "press any key to continue" prompts twice and then automatically closes. An error file is then generated that has the text inside "Error 200: Invalid parameter value specified by user. Use -? option to see help."
I don't want to continue with the instructions because it seems like some sort of actual backup file is supposed to be getting generated and that's not happening.
