There are several reasons to this error, and one being errors in the registry of the client. I’m not going to talk about how to solve that, because there is allready a very nice article on that subject: Word cannot start the converter mswrd632.wpc error on Wincert.net

But one error that this article doesn’t talk about is file-extension errors. And that’s what was wrong in my case. I could open my .doc-file, but the document just said:
%PDF-1.3

This doesn’t make much sense for a normal user, but if you read closely you can can find some lines that can tell you something about the files content. In my case you can see one line saying: “/ProcSet [/PDF /ImageC /ImageB /ImageI]“. This line gives me the indication that this file is not an .doc, but actually an .pdf-file.

So if this is the your case, simply rename the files extention like so:
my_wrong_file.doc => my_wrong_file.pdf

If you have done correctly, you should be prompted with a message asking you if you wanna change the files extension, and to this you click “Yes”, and your all done!

NOTE: You have to un-check the “Hide extensions for known file types”-option in you “Folder Options” (Explorer -> Tools -> Folder Options -> View (tab) -> Advanced settings).

Hope this helps you, and if it did, please take time to comment Maybe you found some other headers? Please do share!
