You can help us out by opening up a Command Prompt, typing powershell $PSVersionTable.PSVersion then hitting Enter. Do you use powershell on your computer?

Just got the same error message when launching Signal Desktop (after launching it again, it updated itself to 1.20.0):

Do you use powershell on your computer?

Yes (e. g. Chocolatey)

The next thing we could try is to try to run the command shown above (maybe choose an arbitrary binary as a target, or a newly-downloaded Signal Desktop installer) and see what the specific error coming back from powershell is.

Which command? This?

powershell.exe -NoProfile -NonInteractive -InputFormat None -Command Get-AuthenticodeSignature 'signal-desktop-win-1.20.0.exe'

If yes, this is the output with a newly downloaded Signal Desktop installer:

Okay, now pipe it to the JSON tool with the rest of the command line: | ConvertTo-Json -Compress

Does this piping work with the cmd console? I've tried the full command before, but this only seems to work without an error (the result is basically the same output as mentioned above, messily formatted) inside of PowerShell. Using the cmd console, I'm getting an error (it says that "ConvertTo-Json" is misspelled or cannot be found).

This page seems to show examples of using it piped: https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.utility/convertto-json?view=powershell-6

In the past we've had problems due to customization of powershell configuration... but this seems a bit like a command just isn't available anymore or something. Maybe the pipe needs to be escaped because Command Prompt is parsing it differently?

The whole thing is strange, because this has worked in the past. Is it a new Powershell version causing the problem? Configuration on a specific machine? Installation source for Powershell, if you're installing via Chocolatey?

Just Get-AuthenticodeSignature 'signal-desktop-win-1.20.0.exe' | ConvertTo-Json -Compress executed from within PowerShell does work, if this helps (lengthy output).

I've fiddled a bit with that command and have something that "works" from within the command prompt (if it really works depends on the desired outcome which I don't know):

Command:

powershell.exe -NoProfile -NonInteractive -InputFormat None -Command "Get-AuthenticodeSignature 'signal-desktop-win-1.20.0.exe' | ConvertTo-Json -Compress"

Output:

The reason that you're getting an error is probably that you don't have the file "signal-desktop-win-1.20.0.exe" (which is just the usual downloadable installer for Signal Desktop) in the directory from which you execute the command.

It does seem to be a quotation thing. Very interesting. Also might just be a breaking change in a new version of powershell causing this, as well.

I got the same error today as reported above. Signal crashed, but when I reopened it it opened fine.

Here's what I get when I run the command in powershell:

@dbolton Though I suppose it could be a problem with the target file not existing on disk when that command is run. Too bad the error message from running that command isn't printed to the console.

So is the theory that the file is actually not there sometimes, and that's why we run into errors?

@scottnonnenberg-signal So do you consider it unlikely that the missing quotation marks as mentioned above could be the culprit?

Looks like the latest version of the powershell exec code does manage all the various arguments better: https://github.com/electron-userland/electron-builder/blob/a0026a7422977b449709f8a662d9dd30600a31b1/packages/electron-updater/src/windowsExecutableCodeSignatureVerifier.ts#L13

As of v1.21.0 we're on a version of electron-builder with those changes, so we'll see what happens when it downloads and tries to run powershell on the next update!

I got this as a rejected promise from another computer: https://debuglogs.org/c46a6ae95b2a185d06d3d4a366a32d43537e8189fd390fb02e2046aa0e215101
