A cannot execute functions inside a 64-bit COM DLL .
Let’s break down the technical reasons behind this error.
Upgrading legacy client infrastructures using Crystal Reports automation frequently introduces this exception when old RDC engines are replaced. PowerBuilder Application Execution Error R0035!
is a critical runtime error that occurs when a PowerBuilder application fails while making a dynamic call to an external object function, typically through Object Linking and Embedding (OLE) or Component Object Model (COM) interfaces. The error code explicitly denotes "Error calling external object function," indicating that while PowerBuilder successfully instantiated or connected to an object proxy, it failed to execute a specific method on that object. powerbuilder application execution error r0035
The is a runtime error that specifically occurs when an application fails to call a function on an external object, typically an OLEObject or ActiveX control . 🛠️ Error Definition Error Code: R0035
Because COM/OLE calls utilize , the PowerBuilder compiler skips syntax and validation checks on any code following the .Object property path. The application only checks if the function exists at runtime, when the compiled code attempts to execute it against the external component. If the component rejects the call, the runtime engine halts execution and throws the R0035 error . ⚙️ Primary Root Causes of Error R0035
If the application crashes on a specific user workstation but works on a development machine, DEP might be blocking the runtime execution. A cannot execute functions inside a 64-bit COM DLL
If multiple versions of PowerBuilder runtimes are installed on a single machine (for example, an older v12.5 runtime alongside a newer Appeon PowerBuilder 2022 runtime), Windows may pull the wrong DLL from the system PATH variable. 4. Database Client Client/Driver Incompatibilities
By methodically checking the library list, validating runtime versions, using Process Monitor, and deploying a robust runtime environment, you can both fix and prevent R0035. For modern deployments, consider containerization or migrating to PowerBuilder 2022 which offers better error reporting and 64-bit support.
Copy all necessary PowerBuilder runtime DLLs directly into the exact same directory where the application's .exe resides. The is a runtime error that specifically occurs
Write script in the event of the PowerBuilder application object to catch and handle the error centrally. This event fires when certain runtime errors, including some OLE errors, occur.
: If the app works in your development environment but fails after deployment, ensure all runtime DLLs and supporting files are included in the application folder or the system path.
Windows prioritizes the local application directory over the system PATH variable, preventing version hijacking. Step 3: Inspect the Windows Event Viewer
A corrupted or unregistered DLL or ActiveX control is a common cause. PowerBuilder cannot call functions from a component that the operating system does not recognize.
