Recently I attempted to install East Asian Languages and files for
Complex Scripts in the Regional and Language options for my Windows XP
Professional Service Pack 2. I tried installing it but a few files were
not found, so I installed it again using a different cd I got from
work. In the process I also changed the Language version of the Non
Unicode programs to Japanese to use some software that required it.
Somehow that must have corrupted my XP because when I rebooted suddenly
I was at a login screen, something that I had never used on my PC
before. When I clicked my name it said Loading your preferences, then
that Loading your preferences disapeared, and I was never able to login
after that. Safe mode took me to the same screen but added
Administrator as well as my name, and neither would login.
I took it back to the shop I bought it from and they installed a
separate installation of Windows XP. They were in the process of re
installing XP on someone elses PC so they used by cd to install on
another PC and it worked fine, so that rules out the CD being faulty.
The second installation of XP has no drivers and no other programs
work, and since it would take a very long time to find all the driver
cds if I could at all, and all the other software I'd paid for would
have to be paid for again if I couldn't find the registrations in the
registry I thought I'd try Repair Installation on the XP I could not
login to.
On running the repair however, I encounted this error:
Error:
The signature for Windows XP Professional Upgrade is invalid. The
error code is 800b0100.
No signature was present in the subject.
***
Fatal Error:
Setup failed to install the product catalogs. This is a fatal error.
The setup log files should contain more information.
Clicking Close will always reboot, and come back to restart this
installation, there is no time to select the second installation which
I can get into as XP always assumes you want to finish the repair
installation. It will always stop at this point and it appears I will
never access this PC normally again.
I have googled this extensively and before anyone points me to this
article here:

The 3 solutions did not work for me
1. I have tried renaming and deleting C:\Windows\System32\catroot2
multiple times, even tried catroot just in case.
2. Not relevand because I am not upgrading from an earlier version.
3. They tested it with different RAM in the shop I bought it from and
it came up with the same error.
I do not want to format the hard drive if I can help it, so if there is
anywhere else the product catelogs might be that needs to be deleted or
if there are any other options to try please let me know.
