To unregister the mswrd632 converter yourself, edit the registry as follows:
Click Start, click Run, type regedit, and then click
Locate and then click the following registry subkey:
For 32-bit versions of Windows: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Shared Tools\Text Converters\Import\MSWord6.wpc
For 64-bit versions of Windows: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Shared Tools\Text Converters\Import\MSWord6.wpc
On the Edit menu, click Delete.
Exit Registry Editor.
This change will effectively unregister the converter and disable it for third-party applications and for Microsoft Office. Microsoft Office will use its own text converters to open these kinds of files
But the problems is we are having many clients. According to this article should each client remove the registry entry itself on his local machine.We are having windows application in .net
Is there any solution in which client don't have to do any thing and problem will fix

this day and age of increased security concerns.
This is something best asked in an IT-related rather than Developer forum, I think. Try on the Technet server:
