I have a serious problem. I'm trying to convert Windows XP Home SP3 Retail French to Windows XP Home SP3 Hewlet-Packard OEM for a buddy of mine. The OS came preisntalled on a laptop he bought from France, so with genuine license and all. The problem is that I forgot to copy pidgen.dll and dpc...dll from the original installation (can't remember the name of the file) and replacing the oem *.cat files aren't helping. His original product key I backed up doesn't work. I knew I had to copy pidgen.dll. Can anyone help me out? Thank you.
