This weekend July 28th my laptop did a windows update. And it went through the regular restarts and when all was done rebooting and loading the final time Windows 10 displayed the following.

Windows cannot find "C:\Program Files\WindowsApps\40459File-New-Project_2.0.4.0_x86__1sdd7...\EarTrumpet.exe'.
Make sure you typed.....
I uninstalled EarTrumpet cleaned the registry, rebooted and reinstalled the program. Before starting the program again, I rebooted and attempted to start the program with the same message displayed.
Please advise?

Hi @rurot10, what build/version of Windows 10 are you using? (Start > Run > winver)
Same thing is happening to me, but a slightly different error message. It seems to happen randomly though and only a Windows restart fixes it.
Windows version is version 1803 (OS build 17134.165).
Version 1803 (OS Build 17134.191)

This might be related to a recently fixed Windows bug. Can you try installing the following patch?

Rafael, the update was already installed on my machine. I again performed an un-install and an install with reboot but with the same message. Any other suggestions.
I was having the same issue as rurot10, even after re-installing KB4340917.
I found a workaround by editing the security settings and making myself the owner of the WindowsApps folder as described here, then launching EarTrumpet.exe manually from the folder:
C:\Program Files\WindowsApps\40459File-New-Project.EarTrumpet_2.0.5.0_x86__1sdd7yawvg6ne\EarTrumpet
Trying to launch it through the start menu throws an error saying "The parameter is incorrect."
Hey folks, sorry to make you jump through hoops here. Can you please do the following so we can gather more data?
Thanks! We've engaged Microsoft on this issue so should have it solved soon.

Got the same issue after updating to RS5. I installed the app on RS4 from the store originally.

This happens to me when I took ownership of my WindowsApps folder. It broke several programs, and I tried to give permission back to TrustedInstaller but it just caused more problems. Based on my research the only way to resolve this is a complete reinstall of Windows.
Microsoft, I own my damn computer. Let me do what I want.
Still not fixed.
I am having this issue now.
I was having the same problem. Removed the app and now I can't reinstall it. The only message I get from Microsoft Store is "Couldn't Install. We'll try again later.".
Edit:
Updated Windows and it eventually got reinstalled automatically.
@riverar did you guys found solve for the problem its been 2 years and no one fixes it!
@Irwinori This is a low occurrence non-reproducible Windows bug, sorry. Are you on an older Windows 10 release by any chance? You'll likely have better success with newer releases of Windows 10.
@riverar am at the last version of windows 10 every app in the store work fine i try to repair it but nothing
pls help i love it and i need it
@Irwinori I just sent another email to Microsoft again. In the meantime, can you use Chocolatey? choco install eartrumpet
@riverar is it save to use because it will be my first time to use it
thank u for ur hard work to making our lives easier
@Irwinori It's safe, we maintain the package ourselves. For more information, see https://chocolatey.org/packages/eartrumpet.
@riverar I install it and its working in a good way, if u can update things up and fix it that's will be cool
