Try to download the current version (31.7.0) and run the installer. https://www.mozilla.org/en-US/thunderbird/

I suggest download from https://www.mozilla.org/en-US/thunderbird/ and reinstall the program "from scratch". This will not touch your existing data.

If that fails, see if http://systweaker.com/step-by-step-fix-icuuc52-dll-error/ helps
