Where is dialog "This app can't run on your PC" stored?

Thank you for your replies guys I'll check this out when I get home. OrthodoxWin32, yeah, when you execute a program through the command prompt it gets executed a different way which avoids SOME of the metro prompts. Files also get executed in this alternate way through 7-zip. You can get the error "the image is valid but for a different machine type" like in Windows 7 when you execute files this way. Idk if it's possible to make files from explorer execute this way, I tried a bunch of things a while ago. I tried making exes execute with a batch file and a batch to exe converted exe by editing the exefile entry in HKCR but it didn't work. Also for a similar thing I tried making another file extension execute a vbs but Windows just refuses to open files with a vbs. However it still doesn't get rid of the metro dialog if you try and execute a 0-byte file or if you try and execute something with an MZ header but not supposed to be executed (like a dll or cpl). So this trick only works for things that would work that are 16 bit programs or files interpreted as such and like arm programs. I guess I will try renaming some dlls and replacing MUIs with "This app can't run on your PC" with "%1 is not a valid Win32 application." Idk if it would show the application name in the dialog box

Actually, it's stored in the last file, pcaui.dll.mui. Though I'm not sure if this information is helpful or not. The other files were there probably because they also contain "This app can't" in other strings.
