Finally, working under Windows (ish).

After much head grinding of teeth and piecing together of various posts I've managed to get the 6.x-2.x-dev release partially working under windows.

1. Install the patched version of 6.x-1.6 (attached)
2. Without "uninstalling" 1.6, delete the files_search folder and replace it with the 6.x-2.x-dev version.
3. Refresh the modules page twice (first time will white screen).
4. Enable the two new modules.

By now you will have the correct tables installed and not get the errors from trying to isntall either of the official 6.x releases.

Next add the various helpers you wish to use. Paths for Windows use the full path to the .exe with "%file% -" at the end:-

c:\xpdf\pdftotext.exe %file% -
c:\antiword\antiword.exe %file% -
c:\swish-e\bin\catppt.exe %file% -

Finally, re-index your search and run cron until it's 100% complete.

You will now have a partially working module \o/

Things still not working are indexing of WEBFM attachments and directory indexing.
