Installed the application but crashes at startup. I installed the Russian version and it works fine (only downside I don't read cyrillic )

Where can I start to find out what is wrong? Strange thing; I uninstalled it and I had to uninstall Stopwatch too (they had some similair pakkage I guess) After installing both I tried reinstalling Stopwatch, but it could not install anymore.....any help advice appriciated!
