After a long Deinstallation and Installation session I have the TMS Component Pack Help in the XE4 Help System (while "unknown Parent namespace:embarcadero.rs_xe4" is still in the log file of reg2help).
What I did (after various tryouts):
- Deinstall Help System (Update 1)
- Deinstall all TMS components
- Clean Registry from all Entries with TMSSoftware included
- Removed Document Viewer 2005
- Removed Document Viewer 2008
- Always Reboot inbetween
- Cleaned Registry with Tool
- Downloaded Help System Update 2 and unpacked manually the included Docoment Explorer and Language Pack for Document Explorer
- Installed TMS Component Pack
- Run Reg2Help as Admin in the Help Directory
Tadaa - at next start of Borland Help it merged your help in.
