N.I.N.A application fails to launch after startup Windows 10

[Former user]

Hello N.I.N.A community,

I recently downloaded the stable (1.7) and then Beta (1.8) builds (x64) on my Windows 10 laptop, and all went well with download and install. However, when attempting to launch the application, the splash screen / N.I.N.A icon comes up, then closes, and the application never launches.

I've verified that my .NET framework is up to date (4.7.2), and it looked like the download successfully updated the C++ Redis packages. I monitor task manager and it doesn't look like anything is really getting kicked off. Lastly, I have tried launching NINA as admin but the same behavior occurs.

The laptop is Dell Inspiron, x64, Windows 10, 12GB RAM, Intel i7 1.99Ghz CPU, all other system requirements appear to be met.

Steps to repro: * *Use my laptop :) * Download NINA * Attempt to launch app * Observe- application fails to launch as expected.

Did anyone encounter this behavior or something similar? Any way to setup tracing or logging to see what's keeping NINA from launching? Thanks!

Best, -Rex

Hi Rex,

can you post what error you get in the Windows Event Viewer?

Hi Stanley-

Interestingly, it appears to be a .NET framework / version error. However, when I attempted to download the 4.7.2 library, the installer failed saying a higher version is already installed. (this was before submitting the issue), additionally, in the windows reg editor, 4.7.2 is showing under:

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft.NETFramework\v4.0.30319\SKUs.NETFramework,Version=v4.7.2

The two errors from event viewer are:

Application: NINA.exe Framework Version: v4.0.30319 Description: The process was terminated due to an unhandled exception. Exception Info: exception code c0000005, exception address 00007FFB88DC57CC

and subsequently:

Faulting application name: NINA.exe, version: 1.8.0.3002, time stamp: 0x5c81a856 Faulting module name: EDSDK.dll, version: 3.8.20.6400, time stamp: 0x5a6aab06 Exception code: 0xc0000005 Fault offset: 0x00000000000457cc Faulting process id: 0x494 Faulting application start time: 0x01d4d7473dc04159 Faulting application path: C:\Program Files\N.I.N.A. - Nighttime Imaging 'N' Astronomy\NINA.exe Faulting module path: C:\Program Files\N.I.N.A. - Nighttime Imaging 'N' Astronomy\External\x64\Canon\EDSDK.dll Report Id: addc139f-39f8-44e8-aa62-ddf06138c07c Faulting package full name: Faulting package-relative application ID:

When trying to verify .NET framework settings through command prompt I get the following:

C:\Windows\Microsoft.NET\Framework\v4.0.30319> .\MSBuild.exe -version Microsoft (R) Build Engine version 4.7.3056.0 [Microsoft .NET Framework, version 4.0.30319.42000] Copyright (C) Microsoft Corporation. All rights reserved.

4.7.3056.0 C:\Windows\Microsoft.NET\Framework\v4.0.30319>

It seems like the actual version being referenced is 4.0.3, but the installer maybe getting hung up on the Build Engine version? Interesting. Thanks for the help and taking the time to assist!

Do you have BackyardEOS or other Canon capture software running in parallel eventually?

[Rex R]

Good thinking Stanley- thus far I have been using BackyardEOS for capture and sequencing. Would you advise uninstalling / removing backyard EOS and then giving it another shot? Thanks!

[Stefan B]

Do you have EOS Utility running in the background? This will prevent the SDK to load properly. Closing this should resolve the issue.

[Rex R]

Thank you Stefan and Stanley- you all are great! It looks like it was EOS Utility and another Canon background app running. Once closed out- N.I.N.A launched successfully. Now time to play. Thanks for the prompt and efficient troubleshooting!
