Description

Seg3D 2.5.0 fails to start under Windows 10

Steps to Reproduce

1. Download Seg3D2-2.5.0-win64.exe to Windows 10
2. Run installer, apparently successfully
3. Run Seg3D2 using its icon in the Start Menu (or from the command line). I also tried running it as Administrator.

Expected behavior: It should start

Actual behavior: An Application Error window appeared saying that the application failed to start (0xc000007b)

Versions

Windows 10 Home 20H2 19042.804 120.2212.551.0

I'll try to replicate this one. It might be the out-of-date Qt libraries used.

[allywarner]

I can't replicate this bug even after updating my Windows OS version. Can you replicate @dcwhite?

[allywarner]

Try with new release 2.5.1

[robertf]

Is 2.5.1 available yet? I couldn't find it.

[allywarner]

@robertf yes! It is now posted! Thank you for your patience.

[robertf]

It still fails to start, the same as before :-(

What kind of machine are you running?

[robertf]

ASUS VivoBook Pro 15 N580GD-DB74, 64-bit, 16 GB

[allywarner]

Do you have another machine to try on?

[robertf]

I have an old Windows 7 laptop that might wake up long enough to try it.

[allywarner]

Let me know what happens!

[robertf]

It can't start because MSVCP140_1.DLL is missing.

[allywarner]

Yes, that's probably too old. We can't reproduce this with our machines. Is there any information when you try to open Seg3D on Windows 10? Possibly on the command line?

[robertf]

When I give this command in the PowerShell:
& "C:\Program Files\Seg3D2_2.5\bin\Seg3D2.exe"
nothing happens, it just returns to the command prompt.

[robertf]

I also tried running it from the Start menu as administrator, with the same result. I've attached a screenshot of the error-message window.

[allywarner]

Is your machine in French?

[robertf]

Partly. When the shop installed Windows 10, they did it in French. When I added my account I did it in English, and the interface is in English, but occasionally bits of French still pop up for reasons I don't understand. It's never caused a problem.

Is your machine running 32-bit Windows perhaps? I suppose it's possible with the complicated setup you described.

[dcwhite]

That web page also mentions updating DirectX, .NET Framework, C++ runtime packages, and various other things. Essentially, this is most likely a machine problem rather than a Seg3D problem.

[robertf]

It's definitely 64-bit and Windows is fully up to date.
.NET Framework 4.8 was installed but not .NET Framework 3.5 so I installed it and then rebooted.
Still no luck :-(
I'll let you know if I find anything that helps.
