Navisworks API - Unhandled Exception Error

Anonymous — Thu, 21 Dec 2017 21:08:40 GMT

I have a console exe that runs from a batch file to generate NWd files from a project list. I usually have it running from a scheduled task from a Windows 4 x64 pc. Although everything was working fine, when I updated some code it quit running from the task. I can double click and it will run fine, but it will not seem to run from a schedule task. I can also run it from with VS 2015 and there does not seem to have any issues or errors. This is the error I get from the Windows log:

Application: XXXX.exe Framework Version: v4.0.30319 Description: The process was terminated due to an unhandled exception. Exception Info: Autodesk.Navisworks.Api.Automation.AutomationException at Autodesk.Navisworks.Api.Automation.NavisworksApplication.Init(Boolean) at XXXX.Program.Main(System.String[])

I am still trying to see what broke when I really didn't do much.

Thanks, Jgarza

You try the "resolver" library

using Autodesk.Navisworks.Api.Resolver;

static void Main()
{
String runtimeName = Resolver.TryBindToRuntime(RuntimeNames.Any);
if (String.IsNullOrEmpty(runtimeName))
{
throw new Exception("Failed to bind to Navisworks runtime");
}
XMain();
}

XMain() is the existing Main function.
