Failed to install Full-Text Search on SQL Server 2008

Question

I'm trying to upgrade my SQL Server 2008 with Full-Text Search feature. Installation fails on it's very end with something like this in C:\Program Files\Microsoft SQL Server\100\Setup Bootstrap\Log\20110318_105034\Detail.log:

Slp: Error: Action "ConfigEvent_SQL_FullText_Adv_sql_fulltext_Cpu64_Install_ConfigNonRC_postmsi" failed during execution.
Slp: Action "FulltextConfigAction_install_confignonrc_Cpu64" will return false due to the following conditions:
Slp: Condition "Feature dependency condition for action: FulltextConfigAction_install_confignonrc_Cpu64 The condition tests feature: SQL_FullText_Adv_sql_fulltext_Cpu64. There are 3 dependant features. The feature is tested for results: ValidateResult, Result." did not pass as it returned false and true was expected.
Slp: Condition is false because the required feature SQL_FullText_Core_Shared_sql_engine_core_shared_Cpu64 failed in result Result

I also failed to upgrade Full-Text Index in SQL server 2008.

The only thing worked for me is to uninstall the SQL server, then I installed it again in 2 stages: - Install only the Full Text Index - then I installed all other features

don't know what was the problem in the first place
