The following solution worked on several of our computers that ran into this
exact same problem. I'll give you a detailed step-by-step procedure since I
have no idea what your level of computer knowledge is.
I ran into the same problem on two of our computers trying to install the
Office 2007 Service Pack 2 issued April 28, 2009.
First you should actually download the service pack file and save it to your
hard drive. You can download it from:
You're going to have to do some simple editing in your registry to overcome
Before going into the registry you would be very prudent to establish a new
System Restore point from the Control Panel (Performance and Maintenance) as
a safety valve.
Using the "Run" command from the Windows Start button, type in "regedit"
(without the quote marks -- I'm using this convention throughout).
Then in the Registry Editor click on File | Export... and export your
Registry to your desktop just as another safety valve.
Now in the left hand window of the Registry Editor go to HKEY_CLASSES_ROOT
Click on the plus sign to the right of HKEY_CLASSES_ROOT to expand the
listings underneath. Meander past all those keys that start with a period way
down to the "Installer" key and expand it too. Underneath it you'll find
"Products". Expand it.
You're going to find a slew of keys with long names like
00002105501100000000000000F01FEC. The first 16 or so are for various
components of Microsoft Office 2007 (if your computer is like our computers,
these will all start with 0000210. You can see what product each is for by
clicking on the lengthy name in the left hand window and looking at the
ProductName in the right hand window. The data column tells you which product
this is for. If it's anything to do with Office 2007, expand the key on the
left window and select the key "Patches". Hit Function Key 2 or right click
and select "Rename". Simply change the name to "Patches_old". Do this for all
of the Office 2007 keys (like I wrote, there are about 16 of them, depending
on your installation). The entries to change include those for Microsoft
Office Shared Setup Metadata MUI (English) 2007; Microsoft Software Update
for Web Folders (English) 2007; Microsoft Office Excel MUI (English) 2007;
etc. -- everything involved in Office 2007.
When done renaming keys you can install Office Service Pack 2 opening your
file manager (most likely the dreadful Windows Explorer) and double clicking
on the name of the file you downloaded. Before installing, be sure to
disconnect from the Internet and turn off your Internet Security/Anti-virus
application and other running applications -- these can, and will, interfere
with installation of the Service Pack.
After the install works (be patient, it takes some time), be sure to reboot.
Go back into the Registry Editor. A new "Patches" key was automatically
created for each registry entry you changed that was invovled in the upgrade
to Service Pack 2. A few of the keys you changed will not generate new
"patches" keys -- for these you should rename them back to "patches". I
strongly suspect that you can then delete the "patches_old" keys, but I am
Good luck. I think this should work for you too.
>> I got the following:
> "UPDATE for 2007 Microsoft Office System (KB67642)"
> The detection, failed, this can be due to a corrupted installation
