Interface Not registered

Starnge issue has started to happen.   When I go to send an email through outlook i receive an interface not registered error message.  If I switch not to use word as my email editor I can send the email.  When I switch it back to use word as the email editor the problem happens again.
Watch Question

What version of Outlook?
Open Start> Run> then type     Regsvr32.exe %Windir%\System32\Ole32.dll in the run box. This will register Ole32.dll in the registry (which is what is needed for Word to be your editor). Let me know if this fixes it.

Hello georgedschneider,

This could happen if you are using incompatible versions of Word and Outlook.  What version of each are you using?

1. Reset the Outlook toolbar template. With Outlook close, do a search for and rename outcmd.dat file. Do the same for frmcache.dat and outlprnt files. Restart Outlook.

Outcmd.dat is located in C:\Documents and Settings\<user>\Application Data\Microsoft\Outlook folder. It is a hidden file, so you have to unhide hidden files. Go to any folder and select Tools > Folders Options > View. Check "Show hidden files and folders". Click OK.

2. If no joy, register two important Outlook files. Go to Start > Run and type regsvr32 OLE32.DLL <-- suggested by cedarghost
Do the same for INETCOMM.DLL

3. If no joy, an addin could be interfering. Disable Outlook Addins.  Go to Tools > Options > Other > Advanced Options > Addin Manager or COMM/Addins and disable the addins.

If you cannot open Outlook, do a search for and rename extend.dat file.

4. Check if an external program running in the background is interfering with Outlook. Check Firewall, antivirus, antispyware, antispam, and all Norton programs. Disable these programs one at a time.

5. If no joy, create a new Outlook profile.

6. Repair Outlook. With Outlook open, go to Help > Detect and Repair.

7. If no joy, reinstall Outlook.  Go to Add/Remove Programs and highlight Microsoft Office. Click on Install/Uninstall.  A menu will pop allowing you to choose repair or reinstall.

Hope this helps!
