On some occasions, when a user tries to open certain Word documents, they may encounter an error that says “Word cannot start the converter mswrd632.wpc”. This is usually due to the file being a plain-text file, but having a .doc extension.
Example: When trying to open a Word document, it gives the above error.
Resolution: The fix for this is simple. Open Regedit and navigate to:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Shared Tools\Text Converters\Import
On the left hand side, you’ll see a key called “MSWord6.wpc” – delete this key. Close Regedit. You should now be able to open this document.
