I installed it with PPT Viewer 2003, but it does't 'see' pptx files. Have you tested this in windows? Do you still run pptviewer 2003, or do you run PPCNVCOM.EXE (this one fails to run because of missing t2embed.dll, haven't investigated that one yet, not near a windows box).
I use it with Office 2003, primarily Word 2003. It works perfectly in Windows--once the converter is installed, Word 2003 can open and save docx files, Powerpoint 2003 can open and save pptx files, and Excel 2003 can open and save xlsx files.
I hadn't tested Excel or Powerpoint in wine before, but I just did, and both ended with an error message about being unable to open the file. Powerpoint's error message specifically complained "No text converter is installed for this file type". So even though the installer says the converter is installed, Word, Excel, and Powerpoint for some reason can't use it.
This problem may be part of a general problem with plugins in Word 2003. The AppDB has one report that specifically mentions plugins not working, and there is an open bug (5264) about the equation editor not working.
