The older Xeltec range of USB Eprom programmers do now work on 64 bit versions of windows, since, according to their own website "working on 64bit platform requires tremendous effort from our side"
So to save their programmers from all of this tremendous effect, here is how to make it happen
N.B. This has only been tested on my PC using my Superpro 280u
with Windows 7,8 and 10 - it should work for you, but everything is done at your own risk!
In the download file, Here, are
the signed driver and support files.
If you need XVI32 you will need to download it from their website.
Xeltek use a standard USB interface chip, an Ez-USB FX2, originally made by Anchor chips, who were taken over by Cypress.
Fortunately, they only seem to have made a single change to the reference driver that was issued by Anchor / Cypress, so as long as a 64 bit version of that driver exists then it should be possible to use the eprom programmer on a 64 bit OS.
A clever guy (Here) has already created a 64 bit version of the driver to use with some other hardware that utilises the same chip, and also sorted out the necessary inf files to allow you to install it on various newer versions of windows. A small change to that inf file, so it recognises the identity of the chip within the Superpro, and that will install the driver.
Another helpful guy, Doug, has now signed the driver file so that you no longer need to do any trickery to let Windows allow you to use the driver - many thanks to him.
finally, you need to make one change to the SP3000.EXE to allow it to work with EZUSB.SYS (rather than their version XEUSB.SYS), and for this you will need a hex editor. I use XVI32, a free download from
Here. using this search for the text
"Xeltekusb-0" (on the latest version it is at offset 0x9B344). This is the name of the driver that it is going to use, and so we need to change this to
"Ezusb-0" and then pad the extra characters out with 00's (Hex 00, not characters!). Save this change and coupled with the driver you should now be able to use your Superpro on the 64 bit version of windows.
