I am running Windows 10x64 Pro Version 1703.

Classicshell instantly crashes, popping WerFault.exe, upon installation.
After installation when I click the start menu I get the default Windows start menu. It's horrible, and I hate it.
I have tried uninstalling and reinstalling multiple times. I have tried using the cleanup utility to remove and reinstall.
Here is the corresponding event in the Event Viewer:

Faulting application name: ClassicStartMenu.exe, version:, time stamp: 0x59907505
Faulting module name: ucrtbase.dll, version: 10.0.15063.413, time stamp: 0x5ba8b66e

The path cited above leads to a .wer file. Let me know if you need that or any additional information.

Let me know if there is any testing you would like me to do.

I tried to capture a procdump and this is what happened:
./procdump -e ClassicStartMenu.exe -w

I attached a dump from the "slow" method.

ucrtbase.dll is the C programming language runtime library DLL that is part of Windows. It might be missing, corrupted or replaced by some wrong version on your PC.

From an elevated command prompt, run the 2 following commands in succession. Let them finish. It may take a while.

Dism /Online /Cleanup-Image /ScanHealth
Dism /Online /Cleanup-Image /RestoreHealth

Thereafter, run this command:
sfc /scannow
Let it finish.

Restart Windows 10. Now see if the crash goes away.

Read the Search box usage guide.

I am a Windows enthusiast and helped a little with Classic Shell's testing and usability/UX feedback.
