I now you are not techinally supporting this tool anymore, but I was hoping to get an update to the fcwin2k.exe tool that would allow us to remap any dll to a new name. It would also be nice if we could do remappings from the command line as it would make it easier to do many files at once. If I had access to the source code, I would do it myself. The dll I have a problem with currently is GDI32.dll. I was trying to use this tool (fcwin2k.exe) to get a Windows 7 app to work on XP, but I got stuck there. If you have any other suggestions that could be helpful, I would appreciate it. Thank you, Shaggee.
