Why am I receiving a mail merge error after the recent Windows XP security update?

Knowledge Article Number 000005414

Customers who have installed the latest security updates for Windows OS's have reported the following errors when trying to use the client side version of mail merge:

Error 1:

Exception: CMMHost::GenMailMerge:Exception Object variable or With block variable not set

 Error 2:


Exception:CMMHost::GenMailMerge:Exception Word cannot start the converter mswrd632.wpc.

 This is appearing in Windows 2003, XP, and now Vista



We have investigated this issue further, and have confirmed that this issue is a side effect of the latest MS security patch that was recently released.  That said, the registry modifications mentioned on the MS article below do work to resolve this issue: 



When testing the steps given, we did find one step that was missing in the article, which may also occur for other machines as well.  If the “Wordpad” option is missing from the mentioned path ("HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Applets\"), it will have to be created manually. To do this highlight the Applets key then right click and select New key. When the key is created type in the name Wordpad.


Once done, the other steps in the article should take care of the issue.
