Hi,

We are currently migrating an application from Sybase PowerBuilder 12.5.2 (WinForm target) to Appeon PowerBuilder 2022 R3 (Classic target).

The migration is complete, and in the development environment:

  • The project runs successfully.
  • The generated XML file correctly points to the installed Appeon runtime.
  • The EXE launches and works as expected.
  • Calls to the external .NET DLL return the correct values.
  • We are using the .NET DLL Importer in Appeon to generate the PowerBuilder function wrappers for the .NET DLL.

Issue:

When we deploy the packaged EXE to a different environment (target machine), the application launches but crashes at a specific point.

Using appname.exe /pbdebug, we observed that:

  • Execution reaches a .NET DLL function.
  • The function appears to loop or fails to return the expected value.
  • The same .NET function works correctly in the development environment.
  • The failure only occurs when running the packaged EXE in the target environment.

What we have verified in the target machine:

  1. .NET Framework 4.8 is installed.
  2. Appeon runtime installed via MSI from the runtime packager.
  3. XML file correctly points to the installed runtime path.
  4. All required DLLs (including the .NET DLL used by the project) are present in the same folder as the EXE.
  5. Files are unblocked.
  6. The .NET DLLs are built targeting x86 architecture and .NET Framework 4.8.
  7. Application launches, but fails when attempting to retrieve a value from the .NET DLL.

At this point, it appears environment-specific and related to the .NET DLL interaction.

Is there anything else we should verify on the target machine that could cause a .NET DLL call to behave differently outside the development environment?

Any guidance would be greatly appreciated.

Thank you.
