Thx for taking care, Don.
I have read through these links weeks ago. None of these "hacks" (the ones I felt safe enough to try) seem to work with me.
The answer that I think is the only solution, is also mentioned on the very page linked to last by you:
It says: "2. Create a 64bit executable and from a 32bit process post messages using WM_COPYDATA."
As far as I understand it, you, Don, need to make a 64 bit seperate little exe (helper app) that will use the iFilters and that hands the results over to XY main. Thats just my understanding though. Any other solution that works is also welcome of course.
