I'm getting an error that it can't load a file or assembly Sybase.PowerBuilder.DataWindow.Interop.dll or one of its dependencies. I have deployed PB Runtimes and PB.Net Runtimes. Any ideas on what I am missing?

Hi Adrian;

  Is that DLL registered in the GAC?

That would certainly register those .NET DLL's!

You should have only needed to install the PB & PB.Net run times. One via the Packager of course and the other, via the "pbruntime.msi" install file located in the "C:\Program Files (x86)\Appeon\PowerBuilder 17.0\DotNET\pbiu\BootStrapper\Packages\1-PBRuntime" folder of the PB 2017 installation.

Yes, I installed both. And rebooted the server. But it didn’t work.

Hi Adrian,


Do you, by chance, have installed the C++ Redistributable Runtime? As well as the Windows Software Development Kit?
