The problem I'm talking about today is trying to upgrade your Windows 7 installation to SP1 by applying Microsoft's update KB976932, called "Windows 7 Service Pack 1 for x64-based Systems" and getting nothing but a failure every time. The same problem may affect 32-bit systems as well, and I'm not sure what the update number for that would be, but the solution should work for either one.

The update starts just fine, chugs along for 10 minutes or so, then reboots the system and starts performing more operations, when suddenly one of them fails about 10% down the road, reboots, and reverts the whole process. You end up with this message (code 80070490) and a failure for which there are a lot of useless "solutions" on the web that just don't work.

Except for one. I can't take credit for it – all I did was spend a month weeding through the crap, retrying, and getting nowhere, until a genius by the name Ben-IS came up with exactly the right diagnosis and provided exactly the right solution. This solution, in my own interpretation, is below.

Step 1

We are going to use a utility called SFC (System File Checker or Windows Resource Checker), which is part of the Windows installation. It will help diagnose the problem.

Open up a command prompt (cmd) as administrator and run

sfc /scannow

This will run for a while and produce a file called CBS.log which you can find in %WINDIR%\Logs\CBS (usually C:\Windows\Logs\CBS). See this KB929833 for more info on SFC and CBS (Component Based Servicing).

sfc /scannow

Beginning system scan.  This process will take some time.

Beginning verification phase of system scan.
Verification 100% complete.

Windows Resource Protection did not find any integrity violations.

Even though there are no integrity violations, we should have enough info in the log to diagnose the problem.

Step 2

Unfortunately, Windows overwrote my CBS.log, so I'll go by the one Ben-IS provided.

Open up CBS.log and look for something like Failed uninstalling driver updates or 0×80070490 – ERROR_NOT_FOUND.

If you have this line, which you should if you're reading this post, you should also see lines similar to these a few lines above:

2011-04-14 12:02:33, Info CBS Doqe: q-uninstall: Inf: usbvideo.inf, Ranking: 2, Device-Install: 0, Key: 598, Identity: usbvideo.inf, Culture=neutral, Type=driverUpdate, Version=6.1.7600.16543, PublicKeyToken=31bf3856ad364e35, ProcessorArchitecture=amd64, versionScope=NonSxS

2011-04-14 12:02:33, Info CBS Doqe: q-uninstall: Inf: sffdisk.inf, Ranking: 2, Device-Install: 0, Key: 599, Identity: sffdisk.inf, Culture=neutral, Type=driverUpdate, Version=6.1.7600.16438, PublicKeyToken=31bf3856ad364e35, ProcessorArchitecture=amd64, versionScope=NonSxS

2011-04-14 12:02:33, Info CBS Doqe: q-uninstall: Inf: sdbus.inf, Ranking: 2, Device-Install: 0, Key: 600, Identity: sdbus.inf, Culture=neutral, Type=driverUpdate, Version=6.1.7600.16438, PublicKeyToken=31bf3856ad364e35, ProcessorArchitecture=amd64, versionScope=NonSxS

One of these .inf files is the culprit, and we're going to find out which one in the next step.

Step 3

Now open up a different log file located at %WINDIR%\inf\setupapi.dev.log (normally c:\Windows\inf\setupapi.dev.log).

Look for a line that contains Failed to find driver update or FAILURE(0×00000490).

Note the exact path to the .inf file that failed. In my case, it was:

sto: Failed to find driver update 'C:\Windows\WinSxS\amd64_usbvideo.inf_31bf3856ad364e35_6.1.7600.16543_none_8a1a2513d42628c3\usbvideo.inf' in Driver Store. Error = 0×00000490

Step 4

This is the key to the whole operation. Open up the command prompt again (cmd) as administrator and run

pnputil – a INSERT_FILE_NAME_FROM_STEP_3

For example, I ran

pnputil -a C:\Windows\WinSxS\amd64_usbvideo.inf_31bf3856ad364e35_6.1.7600.16543_none_8a1a2513d42628c3\usbvideo.inf

You should see the following dialog:

Choose Install this driver software anyway.

The end result should be something like this:

pnputil -a C:\Windows\WinSxS\amd64_usbvideo.inf_31bf3856ad364e35_6.1.7600.16543_none_8a1a2513d42628c3\usbvideo.inf
Microsoft PnP Utility

Processing inf :            usbvideo.inf
Driver package added successfully.
Published name :            oem69.inf

Total attempted:              1
Number successfully imported: 1

Repeat this step for any failures found in step 3.

Step 5

Apply the SP1 Windows Update again – it should now install successfully.

And voila – enjoy your SP1!

Microsoft has failed to fix this incredibly cryptic problem, leaving it up to the users to figure out why their SP1 updates are not installing. Thanks to people like Ben-IS, solutions no longer involve head-banging, postal rage, and f7u12.

The plugin install page provides initial instructions and the location of the plugin to give Eclipse (https://dl-ssl.google.com/android/eclipse/). This is very standard stuff and I've installed many plugins exactly the same way. However, here's when problems started.

Problem #1: Error while loading manipulator

Eclipse just shows a cryptic Install failed box. Here are the highlights:

• !MESSAGE Error while loading manipulator
• java.lang.IllegalStateException: !fwConfigLocation.equals(fwPersistentDataLocation)

It looks like for whatever reason, Eclipse's fwConfigLocation variable does not match fwPersistentDataLocation. I have no idea where those come from and searching for a solution (such as this crazy Japanese sourceforge and this Eclipse bug), restarting Eclipse, and beating my head against the wall took the majority of my the 2 hours I spent on this.

Here's the full log, which will help people with the same problem find it in search engines:

!SESSION 2009-10-15 13:31:40.853 -----------------------------------------------
eclipse.buildId=I20090611-1540
java.version=1.6.0_16
java.vendor=Sun Microsystems Inc.
BootLoader constants: OS=win32, ARCH=x86, WS=win32, NL=en_US
Command-line arguments:  -os win32 -ws win32 -arch x86

Finally, I found a solution that worked – modify eclipse.ini (the one that sits in elipse's install directory) and add the following:

1
2
3
4

-startup
file:/C:/eclipse/plugins/org.eclipse.equinox.launcher_1.0.200.v20090520.jar
--launcher.library
file:/C:/eclipse/plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.0.200.v20090519

Note that the exact locations may differ for you, so figure out what is installed on your machine and replace accordingly.

Also, it seems that the location of the file HAS to be on a new line – otherwise it is not recognized. What kind of shit is that, Eclipse? Some values in eclipse.ini are specified on the same line separated by space, some separated by '=', and some have to be on a new line? This fun trivia fact wasted about 45 minutes of my time.

And yes, startup has 1 dash and launcher.library has 2. /sigh

Edit: it looks like by default Eclipse does come with these options. I somehow managed to lose them, so this is probably my fault. The error couldn't be more cryptic though.

Problem #2: java.io.IOException: The file "C:\eclipse\features\com.android.ide.eclipse.adt_0.9.3.v200909031112-12945" does not exist

Great. Now what…

After examining the features directory, I indeed found that directory com.android.ide.eclipse.adt_0.9.3.v200909031112-12945 does not exist. What I did find though is com.android.ide.eclipse.adt_0.9.3.v200909031112-12945.jar, which is simply an archive. Why didn't you unpack this archive, Eclipse? Or Android plugin devs? Whoever is responsible for this – argh!

After quickly creating the directories and unpacking the .jar contents into them, Eclipse was finally able to install the Android plugin.

If installing a plugin is this friendly, I can only imagine what awaits me in Android app development. Am I the only one with these problems? You let me know.
