    Standard check to ensure the header is valid [valid Win32 application, Import Tables, ] and to get in front of any LoadLib issues. 

     

    Are you getting errors? If you are repackaging a standard installer, you are not likely to run into any issues here. Hopefully you're customer's aren't playing with ResHack, otherwise, nothing to worry about.

    I've not run into any issues yet but I haven't run the tool at scale yet.

    I'm already checking the headers to look for the kernel drivers, printer drivers,16bit files (on x64 OSs) etc. that are unsupported by MSIX.  Was hoping for a list of anything else I may have missed.
