Apps built with Kit 109 and ones that are packaged from builds are portable and do not install any Omniverse runtime code.
Omniverse connectors require an installed Omniverse application. They fail with Kit apps. I have tested extensively with the Paraview Omniverse connector. It fails and crashes Paraview with Omniverse installed app not found error.
How do we fix this problem?

The FAT (default) packaged applications have everything needed to run the omniverse application. Is there a way to share the information needed by the connectors that is contained in the application?
The bigger issue is that the kit 109 dlls are different than the Paraview connector 5.12 dlls. I assume this will be the same problem with other connectors. I assume there is a version of kit that is compatible with the Paraview 5.12 connector. I have not tried other connectors.
Connectors are no longer being worked on and being phased out. All software is now doing NATIVE USD for import and export. Please just use native usd or fbx/stp as a fallback. Please do not attempt to use the connectors as they will no longer work.
For Paraview specifically we have open sourced a small github code sample that allows you to just export out as USD. Please use that until such time as ParaView implements their own.
