SP2 installation

[fabpages]

I can't install windows sp2 pack and neither MS nor Sony want to know about it.
The installation has been attempted fro Web MS Download Site and from CD but hangs at 'Checking product key'.
The error code is 0x87ff0004. MS do not register the error code on their web database and did not wish to talk tome about it refering me back to Sony.
Sony will not deal with the issue either.
Has any one got any advice that may help - Please
Thanks

Hi fabpages and welcome to Club Vaio.

What type of Vaio do you have and does it have the original OEM Operating System installed?

Here is Microsoft Support's solution - I can't vouch for it but it may be worth a try.

SP2 installation hangs at "Checking product key" phase 

There are 3 steps which we have to do to get the SP2 installed.

Steps are:

1) Please go into the CMD prompt (Start/Run --> cmd.exe )

2) Then type cd /d %windir%\inf and make sure we are in that directory.

3) Then type ren oem*.inf oem*.old, it will go back to the prompt after giving you some
error (Do not worry about it)

4) Then type ren oem*.pnf oem*.old1, it will go back to the prompt after giving you some
error (Do not worry about it)

5) Then goto start - run - type "%windir%\inf" and you will see the files in the folder.

6) Then find the file by name INFCACHE.1 and take a backup of it to desktop (by copying it
to desktop) and delete the INFCACHE.1 from c:\windows\inf.

7) Close all windows and reboot the computer to safe mode and start the installation of
SP2 and it should go fine.
