Open SETUPAPI.DLL with XVI32. Sorry, we can't avoid hacking this one!

Some of this information was made possible by the work of 7imo (Tim Ruas). Who now appears to be gone from the 'net I guess.

Click on Address, then Goto. Go to offset 3887h.

In the SP4 version of the DLL, you will see the hex byte sequence '55 8B EC FF 75'.

Replace this sequence with '33 C0 C2 30 00'.

Now save the file and exit the program.
