You can get word converter and excel converter to work by downloading a zip file called microsoft.vc80.crt.zip from the microsoft website or anywhere online.
Extract the contents to the Office12 folder. Basically what this does is creates the manifest file that the converters need to load the c libraries.
Doesn't work for me. I tried it on a fresh install of Word 2003 and FileFormatConverter.exe, and still get the same error. This is on Wine 1.1.0.
