I have version 2.2.0.94 installed (version needed) on a Windows 10 computer running Quickbooks 2018. It's fully updated but we are getting an uncaught exception when it launches.
I have also ran the install diagnostics tool and all came out there as well. We don't have any issues with Quickbooks itself - just the web connector.
Any ideas?
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.
The runtime diagnostics was caused be the missing "Scheduler" key in the system registry.
HKEY_CURRENT_USER -> Software -> Intuit -> QBWebConnector -> Scheduler
After adding that, the issue was that the Quickbooks Company File was moved to a new computer, which meant that the owner / file id values needed to be updated in the .qwc config file before it would load up on that company file.
Hoping this helps out someone else!
