ok so ive made a new xp pro clean with sp2 unnatende insatll.my first iso was the basic install with a winnt.sif file which worked great.

now the iso ive just made witht the same source but with the following changes

Added custom winntbuu.dll

Added CMDLINES

Added Registry Tweaks

Added Start.cmd

Added Alcohol 120%,Office 2003,Nero ,Winrar

Added Custom Theme

Added system Properties Logo and support box

Added Auto User Account Added Crystal Logon screen

Added copy IE Favs

now all of the above have been tested prevoulsy and i know there are no problem wiht the exception of the new winntbuu.dll i added (i used another cusotm one in the past)

Gave me this error at the begining of the insatll.after first reboot where you see the time remaing etc

Error:

The signature for Windows XP Professional Setup is invalid. The error code is 800b0100.

***

Fatal Error:

Setup failed to install the product catalogs. This is a fatal error. The setup log files should contain more information.

could it be the winntbuu.dll?

Hi there,

Me and jcarle are having that same problem (see this post )

So, if anyone could help, that'd be great.

Smudge

ok i resotred the origanl winntbuu.dll and still recived the error so it must be hacked utheme,tcpip etc i put 4 of them inot my cd folder im currenlty re-installing witht the original files

ok ive replaced the origan dl file and the error is still there none of my other changes should have affected it right?

What do the setup log files say?

winntbuu.dll or winntbbu.dll?

I'm asking, cause if its a typo, your making it consitently. Perhaps you named the file incorrectly?

typo. where will the setup log be im using virtual pc 6 and can not acess the drive as this message apears and reboots looping again and agin

im ashamed to ssay this is my 22nd attempt at a working iso...think ive had enough

You can find setuperr.log in the windows folder. As for Virtual PC... I have no idea.

Edit: VPC and not VMWare.

i hope i dont have this problem. i just created one with cmdlines some regtweaks and a custom install background.

Started over with xp gold and slipstreamed sp2 into it

it's working great. thanks

never give up.
