HP Recommended
Product: T730
Operating System: Microsoft Windows 10 (64-bit)

I installed the HP Designjet Utility for a T730 large format printer.  Whenever I print or when I try to run HP Designjet Utility, I get the following error:

 

Microsoft .NET Framework

 

"Unhandled exception has occurred in a component in your application. If you click Continue, the application will ignore this error and attempt to continue.

 

Object reference not set to an instance of an object."

 

When I click Continue it does nothing.  Here is the error details:

 

See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.
