Subject: Batch PLT export from Creo 12 — cpbatch.exe missing, ProPrintExecute returning -22

Hi all,

I am building an automated drawing export system using Creo Toolkit (Creo 12, Windows, DLL architecture). PDF and DXF batch export are working perfectly via ProPDFExport and Pro2dExport. PLT export has been the blocker for 2+ days.

What I have tried:

1. ProPrintExecute — All three option getters succeed (status=0):

• ProPrintPrinterOptionsGet("postscript") ✅
• ProPrintMdlOptionsGet ✅
• ProPrintPlacementOptionsGet ✅

But ProPrintExecute always returns -22 (PRO_TK_BAD_CONTEXT). Window ID from ProMdlWindowGet is confirmed valid (1001). Drawing is retrieved, displayed, window activated and set current before the call.

2. cpbatch.exe — Cannot find it anywhere in our Creo 12 corporate installation:

• Parametric\bin\ — only parametric.exe and cocreatesim.exe
• Common Files\x86e_win64\obj\ — not present

Is cpbatch.exe still shipped with Creo 12 or has it been removed?

3. xtop.exe — Present in our installation. Has anyone used it for headless batch PLT export? What arguments does it accept?

Environment:

• Creo Parametric 12
• Corporate deployment (PTCApps launcher)
• Windchill PDM integration
• DLL compiled VS2022, Release x64, /MD

Any working approach for silent/headless PLT export from Creo 12 would be very much appreciated — mapkey, xtop, batch utility, or any other method.

Thanks
