I'm using PEP version 2.4.23.0 on a Windows 10 VM (VMware Fusion) in my MacBook Pro. PEP was running great for me for years... I hadn't used PEP for about 7 or more months, but I had a need to make a configuration change. I fired it up, made my change, and tried to Download the change to my TSU9400. I got the error below. I searched this forum, and other folks have reported a similar issue, so I tried 3 different things, none of which worked:

1. Reinstall PEP version 2.4.23.0. Note: things that have changed since my PEP was last working include: installation of Visual Studio, update of VMware Fusion Pro from version 10.x to 11.0 and regular Windows updates.
2. Change ProntoDataService to start as a specified account
3. Try to disable HID USB devices

So, I'm at wits end on how to get download to work again.

Anyone have any suggestions?

Thanks...

************** 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:





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.
