Windows 7 Upgrade keeps rolling back to Vista

I finally decided that I would update my desktop from Windows Vista SP2 64-bit to Windows 7 64-bit. So I got my Windows 7 Professional 64-bit DVD, popped it into my PC, and started up the installer and told it to upgrade.

The installer told me that some things may not be compatible with the upgrade, so I cancelled the install and ran the Upgrade Advisor. I uninstalled the programs and removed the drivers it said were incompatible.

The upgrade got to the final step (restoring settings); it got to 92%, but I didn't feel like staring it anymore so I left the room. When I came back, it had rebooted back into Vista with a note saying "Sorry, the upgrade failed."

I Googled a bit and found people had luck after uninstalling things like Wireshark and the ATI drivers. Did that, tried again, still rolled back.

I looked in the logs, specifically C:\$WINDOWS.~BT\Sources\Panther\setupapi\setupapi.app.log, and found the following line. (Each time I try to upgrade the Device in this line is different. This is the most recent log entry, I didn't save the older ones.)

!    cci: !NCI: Op=BIND, Layer=NDIS, Upper=Tcpip6 Lower=\Device\{9A2D9804-A610-4D0B-8B8B-392406EE148F}, Error=00000019

I figured this was a problem with my network devices, so I uninstalled everything (from device manager) except my ethernet port and the WAN Miniports (I can't remove them, when I uninstall them from device manager, nothing happens). I also unchecked IPv6 in my network card's property page.

This still didn't help, it still rolled back after I tried to upgrade.

I know I can (read: should) do a clean install, but I want to get this upgrade to work. Does anyone have any ideas on how to make this upgrade work? I have my graphics card (ATI) drivers uninstalled, all USB things unplugged, all network devices (except my ethernet port and WAN Miniports) uninstalled, all programs the Windows Upgrade Advisor told me to uninstall uninstalled. What could be causing Windows to fail to upgrade and roll back to Vista?

P.S. Just now I found a list of all the Windows 7 upgrade log files: http://support.microsoft.com/kb/927521.

P.P.S. Here is a copy of my C:\$WINDOWS.~BT\sources\Rollback\setuperr.log (which oddly isn't on Microsoft's list of log files): http://pastebin.com/X03Azd5U.

EDIT: I took at look at C:\$WINDOWS.~BT\Sources\Panther\setuperr.log and found this:

2011-10-03 22:19:03, Error      [0x080a97] MIG    HKLM\Software\Wow6432Node\Microsoft\Windows NT\CurrentVersion\Drivers32 [msacm.l3codecp] is not a valid registry value[gle=0x00000002]

Some basic Googling found this thread on Microsoft's forums, maybe it'll help (see page 2). I'm going to try setting MIG_UPGRADE_IGNORE_PLUGINS to bthmigplugin.dll, let's see what happens.

EDIT 2: Here is the full contents of C:\$WINDOWS.~BT\Sources\Panther\setuperr.log (after running the upgrade with MIG_UPGRADE_IGNORE_PLUGINS set to bthmigplugin.dll): http://pastebin.com/ydKFRSL6

Edit 3: I found another SU thread: and as it suggested, installed WinDBG. I did not have C:\$WINDOWS.~BT\Sources\setupmem.dmp, but I did have C:\$WINDOWS.~BT\Sources\Panther\setupmem.dmp. I opened it up in WinDBG, and it said (Full output: http://pastebin.com/3476mx1m):

WINLOGON_FATAL_ERROR (c000021a)
The Winlogon process terminated unexpectedly.

Arg4: 0000000000110bd8

Edit 4: I posted this on Microsoft's forums too: link.

Now we may be getting somewhere!

Edit 5: I looked in C:\$WINDOWS.~BT\Sources\Panther\setupact.log, which is a 136 MB log file, and I found something actually useful.

I tried to do netcfg -e -u ms_netbt_smb and netcfg -e -u ms_rasman, but nothing happened.

C:\Users\NTICompass>netcfg -e -u ms_netbt_smb
Trying to uninstall ms_netbt_smb ...

...done.


C:\Users\NTICompass>netcfg -e -u ms_netbt_smb
Trying to uninstall ms_netbt_smb ...

...done.


C:\Users\NTICompass>

It doesn't seem to want to uninstall. How do I uninstall ms_netbt_smb and ms_rasman?

Edit 6: I removed ms_netbt_smb and ms_rasman by looking through the registry and removing keys that referenced them. Now my setuperr.log is blank, and I'm still getting the cci: !NCI: Op=BIND, Layer=NDIS, Upper=Tcpip6 error. I asked that as a separate question: Upgrade to Windows 7 Rolls Back To Vista, as this one is getting kind of long and messy.

Run the Windows 7 upgrade advisor, see if it flags any software or drivers, remove what is suggests before upgrading.

Edit:

Here are the causes of the 21a error

Mismatched system files have been installed.

A Service Pack installation has failed.

A backup program that is used to restore a hard disk did not correctly restore files that may have been in use.

An incompatible third-party program has been installed.

Source (not for Vista or W7 but may help diagnose)
