I'm having this problem with native messaging (Firefox): If my path to the native manifest (in the windows registry) json contains spaces
e.g. C:\src\Java Signing Addon\Setup\bin\native_manifest.json
then I get the familiar error you would get if using such path in windows cmd:
stderr output from native app lt.dlx.sign: 'C:\src\Java' is not recognized as an internal or external command
The same path works perfectly fine with Chrome
Now, if I wrap the path with double quotes, I get a different error:
"Win error 123 during operation open on file C:\src\Java Signing Addon\Setup\bin\native_manifest.json" (The filename, directory name, or volume label syntax is incorrect.)
Did a lot of googling, but nothing :/
