RE: Error code 0x80070002 on all updates since KB914388



Here is what I discovered. I seem to be lacking the wuauapi.dll file. I
stopped the update service and went to re-register the various files. I got
an error on wuauapi.dll and I discovered that the file is not in the System32
folder nor anywhere else on my PC. I tried to find this file at Microsoft.com
but didn't come up with it. How do I replace it?

Hello

Before reinstalling your version of Windows. I've got a few steps you can
try if you haven't already done so. At the bottom, I have also explained how
Windows Update works.

So - Let's Fix Your Windows Update!
When installing Windows Update, there are 2 folders we need to be concerned
about, CatRoot2 and SoftwareDistribution. These folders contain the Update
Install files, and anything else necessary to download and install your
Windows Updates.

If re-registering the files "wuauapi.dll","softpub.dll", "wuaueng.dll"
,"wuaueng1.dll","wups.dll" do not fix the issue. The next step would be to
rename your CatRoot2 and SoftwareDistribution folders.

Follow these steps and see if it resolves your issue.

Step 1:
Click on Start > Run
paste this into the run line and hit Enter or Ok.

regsvr32 wuaueng.dll wuaueng1.dll wups.dll softpub.dll wuauapi.dll

Step 2:
-Open My Computer > Navigate to C:\Windows\System32
-Rename the folder CatRoot2 to CatRoot2Old
-Close My Computer

Step 3:
-Open My Computer > Navigate to C:\Windows\
-Rename the folder SoftwareDistribution to SDOld
-Close My Computer

Step 4:
Go to Windows Update and try reinstalling the latest updates.

That should fix your issue.

I would definately try that before running any repair installations of
Windows XP.



And now for a bit of Education about Windows Update!
Windows Update uses Delta Compression - a method of updating "partial"
files, instead of rewriting a complete file. You can think of it, as "Why
sent an entire text file to a client - when I just need to send the 1 letter
they don't have". Windows Update - Works the same way.

Thanks
Sincerely

I have 11 updates that have failed to install (both by update download and
manual download). In all cases they give the 0x80070002 error code with the
message about the system being unable to find the file specified. The
Microsoft Tech Support person has run me through several attempts to correct
this, including re-registering all of the files that the updates are calling,
to no avail; the Tech person now suggests that I repair the installation from
my SP1 disk and then reinstall the SP2 update, which will cause several
programs to have to be reinstalled. I think I have read more than a hundred
different methods for correcting this 0x80070002 problem, none of which have
worked. Am I stuck with repairing the installation of Windows XP? By the way,
the attempts to install these updates don;t even create a log file.
