vNext v0.8.0 win x64 only shows spinner

[christophwille]

I double-click the executable after extraction from the x64 zip archive (unblocked first). The window launches full-screen, I get to see a spinner in the middle and that's it.

Windows 10 with latest patches. "Normal" 0.8.0 starts just fine.

Thanks for reporting. Do you see the same issue if you use the installer (.exe) instead of the zip file?

[christophwille]

MSI: requires elevation to admin privileges, so sorry, cannot test that.
EXE: can install. But, on running, Crowdstrike Falcon killed the process (didn't do that for extracted one) on first start, second start - again, only spinner.

Same here via the win64 MSI installer.

The spinner does eventually timeout with the message:

Oops..
NetPad backend did not start after waiting for 30150ms.
Will stop trying.

Looking in the event log I saw I was missing a runtime dependency:

Description: A .NET application failed.
Application: NetPad.Apps.App.exe
Path: C:\Program Files\NetPad vNext\resources\netpad-server\NetPad.Apps.App.exe
Message: You must install or update .NET to run this application.

App: C:\Program Files\NetPad vNext\resources\netpad-server\NetPad.Apps.App.exe
Architecture: x64
Framework: 'Microsoft.AspNetCore.App', version '6.0.0' (x64)

The following frameworks were found:
8.0.8 at [C:\Program Files\dotnet\shared\Microsoft.AspNetCore.App]

To install missing framework, download:
https://aka.ms/dotnet-core-applaunch?framework=Microsoft.AspNetCore.App&framework_version=6.0.0&arch=x64&rid=win-x64&os=win10

I uninstalled Netpad & installed the missing framework but I still get stuck on the spinner => timeout message.

[tareqimbasher]

The .exe installer actually runs in user mode and is configured to only do user installs. So if you haven't already tried it, give it a shot.

Besides that, here are some things to try:

• Can you check if Windows Defender is blocking something about the app?
• Can you run the app from a terminal (preferably git bash if you have that, or PowerShell/CMD otherwise) and see if you see any issues in the output.

[tareqimbasher]

@AlexKeene thank you for reporting. I'll check this out.

[sjsepan3]

Same thing here with the .deb package on Linux Mint 21.3; after a while it times out with:

Oops..

NetPad backend did not start after waiting for 30150ms.
Will stop trying.

Regular v0.8.0 package installs / runs normally.

@sjsepan3 can you try installing .NET 6 runtime or sdk and see if that fixes the issue for you?

[sjsepan3]

@sjsepan3 can you try installing .NET 6 runtime or sdk and see if that fixes the issue for you?

6.0 SDK is already on my system. Also, just decided to follow your advice to @AlenKeene and run from terminal, and got output below, followed by app starting OK (that is after failing 3 times starting from menu.). Starting from menu again still times out...but starting from terminal again still works.

Output from 3rd run from terminal (netpad-vnext &) with it still running.

Note: the & is so I get back control at the terminal, but the previous runs from the terminal, which also worked, were without the &, so that doesn't affect it. I cannot tell why running from the menu entry (netpad-vnext) fails but same command from the terminal does not.

@tareqimbasher UPDATE: the linux menu editor has an option to "Launch in Terminal", but when checked (it is not by default) it still times out. So, still somehow different than manually running in terminal (bash).

[tareqimbasher]

Thank you for the details. I'll take a look and see what's going on. @sjsepan3 is the AppImage giving you the same experience?

[sjsepan3]

Thank you for the details. I'll take a look and see what's going on. @sjsepan3 is the AppImage giving you the same experience?

I will try it out tomorrow and let you know ...

@tareqimbasher OK, so the same vnext AppImage exhibits that dual behavior: when run from the desktop launcher in the menu(~/username/.local.share.applications/NetPad/netpad_vnext-0.8.0-linux-x86_64.AppImage) it times out on startup, but when started from the terminal (./netpad_vnext-0.8.0-linux-x86_64.AppImage) it starts fine.
So I think I'll alter the command in the launcher to cd to the directory and then run from there...BRB.

UPDATE: so I can start the app from the terminal at ~ (home/username) with cd /home/sjsepan/.local/share/applications/NetPad && ./netpad_vnext-0.8.0-linux-x86_64.AppImage, but the desktop launcher editor dialog will not accept that, and if I edit the .desktop file in Pluma editor, it won't load into the menu and running the launcher directly gets 'There was an error launching the application'. Alll of that is to say that the launcher doesn't like the compound command. even though it is valid.
The reason I tried this way is because I suspect the difference in behavior between the menu the terminal is the location where I start the app.
UPDATE2: However, starting in the terminal at ~ and using /home/sjsepan/.local/share/applications/NetPad/netpad_vnext-0.8.0-linux-x86_64.AppImage, it works, so ...I don't know.

[tareqimbasher]

Thanks @sjsepan3 for the update. It must be having a problem getting the path where it's located.
