The 2 files that need to be renamed (either manually or through a batch file) are uflcapw.dll and ufldtdif.dll. They are both in the c:\windows\crystal directory. Also note that QRWin installs uflmask.dll which is known to interrupt A4W Ap check printing sometimes, so be aware that this is another file that needs to be renamed as well.
