Possibly a typo in the code.

[aleksey-r]

The parameter "culture" for the Russian language is ru_ru instead of ru-ru.
https://github.com/volks73/cargo-wix/blob/master/src/lib.rs

Cultures::RuRu => write!(f, "ru_RU"),
...
"ru_ru" => Ok(Cultures::RuRu),
...

Result of "cargo wix -c ru-ru" execution:

Error[2] (Generic): Unknown 'ru-ru' culture

Result of "cargo wix -c ru_ru" execution:

Error[1] (Command): The 'light' application failed with exit code = 102. Consider using the '--nocapture' flag to obtain more information.

Thank you for the bug report. Yes, this is a typo for the Russian culture. It should be a dash/hyphen not an underscore. It is an underscore in two separate places in lib.rs. I am in the process of fixing and look to a get a bugfix release shortly.

[volks73]

Fixed as of 508e3e1.

Creating a new release shortly.
