We have a client using our application through a Citrix environment, although they state it happens locally too, when they print reports it crashes once they moved to a Server 2016 environment but doesn't happen in Server 2008.  The dll it is crashing on is pbSCN17.dll (crashes in PB 12.5 as well pbSCN125.dll) which is the SQL Native client dll.  Anyone else having any issues with Windows Server 2016 and this dll crashing when the datawindow is retrieving data to render to the screen?

Hi Tina,

We’ve never had such issue. PB also supports deploying exe to Windows Server 2016.


  1. What is the version number of your SQL Server Native Client installed on your machine? What is your database server version number? Is your exe built into 32bit or 64bit?
  2. Besides DW retrieve, do you have such issue in other areas, such as SQL, DW Update, etc.?
  3. If you run it in other Windows Server 2016 machine, do you get the same issue?
  4. Have you tried starting your exe using ‘Run as administrator’?
  5. Did you install PB Runtime package on your machine? I suggest that you install it and see if it resolves the issue.
  6. Please try copying your exe & pbd files to the PB Runtime install folder and see if it resolves the issue.
  7. If you change your application to use OLE DB, ADO.Net or ODBC to connect to your database, does it resolves the issue?

If none of the above resolves your issue, I suggest that you open a ticket and provide the environment information and reproducible test case in Appeon Support ticket system: https://www.appeon.com/standardsupport/newbug.

Hi Ken;

I wonder if this issue is unique to Tina's Citrix environment?
