we are able to build and register the dll successfully.
but search is not working.
Here is filtdump error:
filtdump.exe "C:\Users\xxxx\Desktop\SampleFile.filtersample"
FILE: C:\Users\xxxx\Desktop\SampleFile.filtersample
IFILTER: LoadIFilter failed, hr == 0x80004005
IFILTER: SHCreateStreamOnFileEx failed, hr == 0x80004005
LoadIFilterWrapper failed, hr == 0x80004005

Research direction

Start with the WindowsSearch/IFilterSample sample and reproduce the reported filtdump.exe command against SampleFile.filtersample. Done means the filter loads successfully, filtdump.exe no longer reports 0x80004005, and search works for the sample file.
