I'm seeing the same thing. Looks like this is an issue when Squirrel.Windows tries to parse the release file. It seems that it's treating the URL as a local path to the nupkg and expecting a semver string which is not present in the download URL.

Did you end up finding a solution @rizwan92?

[rizwan92]

you need to buy code signing certificates to make it work

[sergeichestakov]

Hmm our app is signed.

Anyways we ended up figuring it out - we just needed to update the download URL in the release file to end in the .nupkg filename, including the version, rather than a more generic link.
