". It occurs when a PowerBuilder application fails to execute a method or access a property on an external component, most commonly an OLE (Object Linking and Embedding) Experts Exchange Primary Causes Missing or Unregistered Components
| Strategy | Implementation | |----------|----------------| | | Never hardcode C:\ or \\server\ in project library lists. | | Automated Build Scripts | Use PowerBuilder ORCA (Open Runtime Call Interface) to compile from CI/CD pipelines and verify all PBDs are generated. | | Pre-Launch Health Check | Write a small utility that checks file existence, size (>0 bytes), and version stamp before launching main EXE. | | Shadow Copy Deployment | Deploy new version to a new folder, then update a symlink. This avoids "file in use" errors and missing PBDs during cutover. | | PBD Merging | For final production builds, merge all PBDs into one or two large PBDs. Fewer files = fewer chances for R0035. | powerbuilder application execution error r0035
