I execute a program on Windows 10 x64 and works fine, but I execute the same program on Windows Server 2012 R2 x64 and get "Could not find a 32 bits IFilter dll for a file with an '.pptx' extension"
The program is a C# program that use IFilter to parse some files and get the text
I download all the Update for Microsoft Filter and still not working
The app was working in Platform target: "Any CPU" and Prefer 32-bit so the app search for the 32 bits dll.
Just uncheck the Prefer 32-bit and change the Platform target to "x64" for the project
