Hardware update wizard not working


I'm having difficulties installing a wireless usb wifi adapter (Realtek rtl8187).
On my other pc (also Windows XP) it works perfectly.

I keep getting this message;
"Cannot Continue the Hardware Update Wizard"

I've tried everything I could find on the internet including reinstalling Windows XP but it can't find the driver.
Does someone knows what goes wrong here?

Thank you!

The messages I get;

USB device not recognized

And then when I try to update driver;

Cannot continue the hardware wizzard
The wizzard could not find a better match for your hardware than
the software you currently have installed.

Any tips for me?
Thanks for your reply!

I've the correct driver because it works fine on my other desktop pc (using also Windows XP (sp3)).
The desktop pc brand is Olidata model Denver 32bit.

And I've tried to search the internet for a solution and normally I find but not this time so I looking for help at this forum.
