XP is 32-bit.
Maybe localization have influence. My XP is Norwegian.

After much personal expense (buying a Uno) and much loving crafting of screen shots, heres how to get from john.olsen's position to a working system on windows XP.





















Do you like the kinky double mouse pointers on some of 'em ?

After the good news, I've run into issues with serial with the Uno (like lots of other people), so I'm of the opinion the ol' Duemilanove is better

*SOLVED* (for me)

I just received my Arduino Uno yesterday and had been struggling to get the driver to install on my laptop Windows XP machine (worked fine on my desktop WinXP machine).

I was getting the exact same problem as john.olsen describes (a few posts prev.).  I would point windows to the driver location, it would copy it over, and then complain "The system cannot find the file specified".  Arduino Uno would be listed in device manager under ports but it would be disabled, and no COM# was listed as part of the port name.

The fix that worked for me... (found here: http://forums.techguy.org/1680041-post1.html)
 1.  Start -> Run -> "regedit"
 2.  Nav to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion
 3.  With "CurrentVersion" selected, choose menu option "Edit -> New -> Key"
 4.  Name the key "RunOnce"
 5.  Reboot (may or may not be required... I didn't try without rebooting)
 6.  Connect Arduino and install the drivers according to the instructions.

After doing this the installation went as expected.  Hope this is useful to others.

pluggy: thanks for the great screenshots!

I posted them here: http://arduino.cc/en/Guide/UnoDriversWindowsXP and linked to them from the main instructions: http://arduino.cc/en/Guide/Windows.  Let me know (by forum PM) if you have any problems with this or would prefer some other form of citation.

<solved>
Mitch,
Thanks for your your post.   Was troubled by the driver install issue on XP.  Your post solved the problem.  This does seem to be a real issue on Win XP.  I will repost the fix for those still having problems:
jumblo

Symptom: I would point windows to the driver location, it would copy it over, and then complain "The system cannot find the file specified".  Arduino Uno would be listed in device manager under ports but it would be disabled, and no COM# was listed as part of the port name.

Solution:

1.  Start -> Run -> "regedit"
2.  Nav to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion
3.  With "CurrentVersion" selected, choose menu option "Edit -> New -> Key"
4.  Name the key "RunOnce"
5.  Reboot
6.  Connect Arduino and install the drivers according to the instructions.

After doing this the installation went as expected.

I was having the same problem. Have been trying to install the FTDI drivers from their website for a couple of hours now (as described in the ladyada.net tutorial). It seems all of that was a waste of time, and that I needed to point my computer to the drivers folder within the arduino folder that i had installed. All is good now.
