microsoft support id 938810

i refer to this support id on microsoft website.
I have problem opening one word document after installing sp3. The solution given on the website is as follows.

To enable Office 2003 to open files that are saved in previous Word file formats, follow these steps: 1. Click Start, click Run, type regedit, and then click OK.  
2. Locate and then click one of the following registry subkeys: " HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\11.0\Word\Security\FileOpenBlock
" HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Word\Security\FileOpenBlock
3. Double-click the FilesBeforeVersion registry entry, type 0 in the Value data box, and then click OK.  

However, i can't find the FileOpenBlock as mentioned in the registry.

Extract from that site:

If the FileOpenBlock subkey does not exist, follow these steps to create it:
a.  Click to select the Security subkey.
b.  On the Edit menu, point to New, and then click Key.
c.  Type FileOpenBlock, and then press ENTER.
5. On the Edit menu, point to New, and then click DWORD Value.
6. Type the DWORD name that you want to restrict, and then press ENTER. For example, type BinaryFiles.
7. Right-click the DWORD name that you typed in step 6, and then click Modify.
8. In the Value data box, type 1, and then click OK.
9. On the File menu, click Exit to exit Registry Editor.
Hi, You need to create that registry key. This is case sensitive so be carefull.


There is a section that describes for Word 2003 hot to create the required keys.

ok, you need to add the key "Security" too.
run regedit, go to HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Word
This is where you cannot see "Security"
on the Edit menu select New Key and enter the name as Security
Now proceed with the extract of instructions above.

Remember to be carefull, it is all case sensitive.

Ok, thanks, managed to do so.. but i actually want to allow able to open files before sp3 updates. so have to create DWORD name FilesBeforeVersion with value 0
No, that is only for word 2007, what you have done is enough to be able to open older version documents with word 2003. Have you tried it?
