The windows installer bundlers, the WIX and MSI installers, don't work when the APP_NAME (or one of several other bundler arguments) are set to non-latin values, such as cyrillic text. These appear to be limitations in InnoSetup and WiX Toolkit. InnoSetup(EXE) appears to be more fixable than WiX, but both have been broken since the first release of packager.
