Yanfly is an Unknown Publisher... Huh?

All of a sudden, my comp won't recognize Yanfly scripts. I'm not exactly sure what to do here. Help?

It is trying to open it in a way it would an exe. Go to Notepad and open it from there.

Yeah. Before it wouldn't open them, but now it wants to open all of them when I try to install them. But I don't want to open them at all.

All I want to do is move the file.

I switched it over to Notepad. It changed all the files over to Notepad's icon, but nonetheless, they still work. Still, don't know what happened though.

What happend is pretty much what JtheDuelist said it tried to execute the (java)script within the "YEP_BattleEngineCore.js" file but as it isn't exactly a file meant to be run/executed by Windows (your computer) you got that error.

Why it tried to execute it is perhaps you accidently double clicking the script causing the computer trying to execute it you usually get a prompt asking if and or how you want to use the file but if i remember corectly you can also disable this prompt.

You maybe are trying to move it to your project map by drag and drop but in your case, you are saying they all open thus perhaps you have the function enabled on your pc to open/execute a file with a single click instead of a double click in this case you might want to start using "CTRL+C" copy "CTRL+P" paste.

The icons all changing to notepad means that when tryin to execute the .js file you got a prompt asking how you would like to run a file like this you choose notepad and thus changing al .js files icon to that of notepad.

I hope i have explained the possible issue clear enough.
Have a nice day.

Thanks.

I'm back again cause i received the same error you received this time.
I wanted to check out a plugin so i wanted to copy it to a random project and the error popped.

It wasn't caused by what i initially thought it was.
For some reason the plugin file interacted in this way because you wanted to past it while you had another .js file selected thus pasting it within the file(if it was a map. it didn't really do this.) and then throwing that error.

I also have no idea what what it tried to do.
This is just my guess but i think it tried to run the copied .js file with the selected .js file but i'm not sure.
