I have put in a new mother board and processor, psu
memory etc. Windows requests activation but
i receive no on screen "installation id", does
this imply that windows can't create the hardware
hash code and that perhaps a key piece of hardware is missing?

any ideas?

You need to boot to Windows XP CD to reinstal Windows.

i_XpUser

i am past the install, i am trying to activate.

Is your XP genuine?

i_XpUser

ep , got to the elusive live person at ms,
but on screen where there should be
and installation id to pass to Call Center
it's blank, they can't help, they asked
me to reboot, which makes no difference.

So I assume that there is something wrong with
my pc set up.

I persued this through the microsoft site.

The istallation id is made up from the product key
and a hash key, there is a method GetInstallationId()
which yields nothing on my machine, comes up blank?
i created a script calling this method and it yields
'0'.

that's a yep. According to the documentation
the hardware hash is derived from the
following hardware identities

1 Display Adapter
2 SCSI Adapter
3 IDE Adapter
4 Network Adapter MAC Address
5 RAM Amount Range (i.e. 0-64mb, 64-128mb, etc)
6 Processor Type
7 Processor Serial Number
8 Hard Drive Device
9 Hard Drive Volume Serial Number
10 CD—ROM / CD-RW / DVD-ROM
11 "Dockable"

i am assuming that post my hardware change
a value is missing

"i am past the install"

If that was not a clean install, I hope you did some saving before changing the hardware. Because I think it's gonna take a clean install now.

Do yourself a favor BACKUP!!!

kim kommado says xp will not install on priates versions

is it a pirate version?
