I’m currently in the process of upgrading the RealDWG DLLs used by my application from v18.2 to v24.0. This has involved upgrading a number of projects to .NET Framework 4.8 and to 64-bit.
After upgrading I get the error “There was an error reading from the pipe: Unrecognized error 109 (0x6d)” in EventViewer when
RuntimeSystem.Initialize(new DWGHost(), 1033);
is executed.
Can anyone help me determine what might be causing this? Any help is greatly appreciated.
