Hi, NetPad 0.6.1-win-x64 suddenly stops starting today on my Windows 11 machine. Could you please investigate what went wrong and how I can make it work again. Below are all information that I think are helpful for troubleshooting. Thank you.

[Window Title] Error

Thank you for reporting this. As a test can you try installing .NET 6 SDK and see if it launches without an error?

I started getting this error today too, I'm not able to run NetPad anymore. Tried upgrading to latest NetPad version and reinstalling it with no help. FWIW, I'm running Windows 10.

I assume downgrading to 0.6.1 doesn't help? Could you try going over your network interfaces and seeing if disabling any of them fixes the issue? See: #111

Also linking this SO answer if it helps: https://stackoverflow.com/questions/59428844/listen-eacces-permission-denied-in-windows

I haven't been able to replicate the error which makes it really hard to figure out a cause and solution.

Ok. I tried disabling some of my network interfaces and it seems that this is the problem: image Disabling my wireless interface fixed it for me. And even after renabling it Netpad will start normally now.

Weird :D

tareqimbasher commented 3 months ago

Great! Thanks for reporting back. Seems to be some network interfaces are keeping ports busy or inaccessible somehow on Windows.

Closing as environment issue. I added an entry to Troubleshooting page
