Launchbox Crashed: Could not load file or assembly 'Microsoft.Toolkit.Uwp.Notifications. The system cannot find the file specified.

[Michael Michael]

I was using LaunchBox to run DOSBOX. When I exited the program: Impulse Tracker (an awesome DOS Music tracking program), it gave this failure. It’s possible that DosBox had developed a memory instability since it had been running overnight, and included multiple sessions of the computer going to sleep, and at least one full hibernation.

I haven’t seen Launchbox crash like this very often, as Launchbox is quite stable. I’ll keep my eyes open though.

What operating system are you running?

Windows 10 with the latest updates

Launch box generally runs very stable on my machine. Exception failures like this one are rare, so I’m not too concerned. Generally Impulse Tracker runs just fine (in a native DOS environment at least), so running this virtually through Docs box is new, even though I’ve used icebox for many years.

Previously in dosbox, I have used scream tracker in the past which also happens to be a music composition MOD tracker program.

I’ll keep my eyes open and see if I continue to get errors like this, and if I can provide additional context. Primarily I submitted this crash data to provide a scenario that others might be experiencing with certain applications. I’m guessing that DOS Box must not have exited gracefully. Let me know if you need anything else!

Thank you!
