KFXConverter process quits without any error message

Article # 3036089 - Page views: 40


KFXConverter.exe does not post any error (even when starting it directly from a command line) and quits without doing anything.
When used in document conversion the conversion job fails with an error like this in the TCLINK trace:

05/18:27:56.725 (1d64/09fc) KFXConverter::Thread_executeKfxConverter KFXConverter Command Execution successful
05/18:27:56.725 (1d64/09fc) KFXConverter::Thread_executeKfxConverter() <--- Returned: Failure
05/18:27:56.725 (1d64/0af4) KFXConverter::fStartConversion: 401, PDF file C:\TCOSS\TCLP\TMP\TCLINKMX7\1234567890.PDF is not generated.
05/18:27:56.725 (1d64/0af4) Please check source file path, batch file path and batch file


On the TCDCLINK machine FIPS mode could be enabled in the windows registry:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\FipsAlgorithmPolicy\Enabled = 1

If this is the case, current version of KFXConverter may need a KFXConverter.exe.config file that disables enforcing of FIPS policy until an updated version exists that solves that problem.


Installing KFXConverter from patch 15009 may fix the issue as it contains a KFXConverter.exe.config that contains the following configuration part:

        <enforceFIPSPolicy enabled="false"/>
