This dll is for LabVIEW web services. Are you using web services on a remote machine? It is possible if you built an installer that the files were not copied correctly.

1. From labview\resource\webserver\modules\ copy the following files:
   • libopenSslModule.dll
   • libsslInitModule.dll
   • libsslModule.dll
   
   And paste them into the following directory on the target computer:C:\Program Files\National Instruments\Shared\LabVIEW Run-Time\2009\webserver\modules\
   
2. From C:\Program Files\National Instruments\Shared\nissl\ copy the following files:
   
   • NIlibeay32.dll
   • NIssleay32.dll
   • nisslinit.dll
   
   and paste them into the same directory on the target computer: C:\Program Files\National Instruments\Shared\nissl\
   
3. Ensure that the certificate and key files located in the directory specified in the niwebserver.conf file.
