If I change the "language for non-unicode programs" to english in control panel -> region, index manager works without any errors on the same PC. Then I compared the index files before and after the language change. I found the difference is in the index_settings.xml (after base64 decode) tag NormalizeQuotesList. If I replace the bad index_settings.xml created in non-english windows with the good one created in english windows and set the language back to to non-english, index manage works. So the problem is in the index creation step, I guess.
