Hi Anton;

  Yes, the PB 9 compiler was tightened up a lot since V9.x in the 10 thru 12.6 versions of PB. Not only that but the PFC was tweaked quit a bit in the 10.x versions to also accommodate not only this type of issue but also to adjust for the Unicode realm (which PB >=10.0 is Unicode).

  Instead of migrating the PFC from whatever version you were using in PB 9.x, I would strongly suggest that you replace the PFC layer (not PFE layer) with the latest version of the PFC from GitHub to correct this issue and even more potential issues from using the old ANSI version of the PFC.

HTH

Regards ... Chris

Thank you for your response - will have to dive into the PFC layer....

Hi Anton

simply changing the PFC won't fix your problem. In your extension object nep_n_cst_dwsrv_printpreview you have to change the variable for the platform from n_cst_platformwin32 to n_cst_platformwin. f_Setplatform creates the variable type based on the environment.
