+Install-PCDMISPDFConverter.ps1
+
+Installs the PC-DMIS PDF converter (Amyuni Document Converter 500, printer name
+"PC-DMIS 50 Converter").
+
+Why this exists: our CMM image installs PC-DMIS from a patched STANDALONE MSI,
+bypassing Hexagon's Burn bundle. The Amyuni PDF converter is NOT a custom action
+in the main MSI (INSTALLPDFCONVERTER is a bundle property the MSI never reads).
+The bundle would have run the Amyuni install as a separate chained step - which
+we skip. The MSI does lay the installer down on disk at:
+  C:\Program Files\Hexagon\PC-DMIS <ver> 64-bit\PDFDriverInstallFiles\BatFileInstallPDF50.zip
+but nothing ever executes it. This script does.
+
+The zip ships InstallPDF50.exe + the Amyuni driver (amyuni.inf, acfpdf*.dll,
+cdintf*.dll, atpdf500.cat) + InstallPDF50.bat. We do NOT run the .bat (it ends in
+`pause` and hangs under /qn) - we parse its InstallPDF50.exe invocation (printer
+name + Wilcox licensee + license code) and run that directly from the extracted
+folder so the sibling DLLs resolve.
+
+The converter is ONE system printer shared by every PC-DMIS version, so we install
+from the first PDFDriverInstallFiles we find and stop once the printer exists.
+
+Idempotent: if the "PC-DMIS 50 Converter" printer already exists, exits 0 without
+reinstalling. Run as administrator / SYSTEM (driver install needs it).
+
+Exit: 0 = printer present (installed or already there), 1 = failed.
