I used PlayOnLinux 3.4 in SuperUbuntu Interpid. I installed Cuneiform. When I try recognize any document I send a message: "Error in module <KERNEL32.dll>. How can I solve this problem?

Did you changed Wine version for Cuneiform under Tools->Manage Wine Versions->My applications ?
If you did so change it back to 0.9.45 or any other version which was tested and works here

Thanks for the help. The best results I have if work system version of the Wine. But, after some minutes of work I see the same message. Possible reason is that I trying to recognize cyrillic font?

If it doesn't crash at recognizing latin fonts then that is a bug with Wine or Cuneiform and if you will you can post bug here
