Subject: [Snort-users] Win32: failed to initialize dynamic preprocessor: sf_sdf (ipv6)

There seems to be an issue with the Win32 version of the Snort. After installing a fresh development site for testing and using only the files from the latest Snort, Version 2.8.6-ODBC-MySQL-FlexRESP-WIN32 GRE (Build 38). Upon running Snort, there is a failure with; failed to initialize dynamic preprocessor: sf_sdf (ipv6), and Snort quits.
I’m thinking there is a problem with the preprocessor that is associated with the sf_sdf.dll file. I’ve seen some other inquires about this same problem.
It seems that removing the file from the folder is the only way to allow Snort past this issue.
Looking at the Snort guide, I see no direction past this problem. I’m not sure if it’s a configuration issue that I’m missing, or just a faulty dll?
Can anyone shed some light on this issue?
File Information:
Snort version (-V): Version 2.8.6-ODBC-MySQL-FlexRESP-WIN32 GRE (Build 38)

File: sf_sdf.dll
CRC: 9E771F6D
MD5: C223BB52D469244C8E21B0DAE05AE1C8
Kindest regards,
