[fireball] 44116: [Unused ReactOS setup] - Move duplicate code from LoadSetupData to a separate function - Fix a bug on line 1054 of the original file: SetupData.LangCount should be SetupData.KbLayoutCount (copy-paste mistake). This would have probably gone unnoticed if SetupData.LangCount > SetupData.KbLayoutCount due to other end of section checking. - Based on a patch from bug 4933.

[Unused ReactOS setup]
- Move duplicate code from LoadSetupData to a separate function
- Fix a bug on line 1054 of the original file: SetupData.LangCount should be
SetupData.KbLayoutCount (copy-paste mistake). This would have probably gone unnoticed if
SetupData.LangCount > SetupData.KbLayoutCount due to other end of section checking.
- Based on a patch from bug 4933.
