Example after installing TMS Web Core:
Computer\HKEY_CURRENT_USER\Software\Embarcadero\BDS\19.0\Library\Win32\Package Search Path
$(BDSCOMMONDIR)\Bpl RSXE11 (???)
D:\tms\Products\registered\TMS WEB Core
D:\tms\Products\registered\TMS WEB Core RSXE11
D:\tms\Products\registered\TMS WEB Core RSXE11
D:\tms\Products\registered\TMS WEB Core RSXE11
D:\tms\Products\registered\TMS WEB Core RSXE11\Component Library Source
D:\tms\Products\registered\TMS WEB Core RSXE11\Component Library Source

D:\tms\Products\registered\TMS WEB Core RSXE11\Win32
D:\tms\Products\registered\TMS WEB Core RSXE11\Win32
D:\tms\Products\registered\TMS WEB Core RSXE11\Win32
But that's not all in the registry. So I'm cleaning.
I almost reinstalled Delphi Tokyo..

These identical entries are of course not needed.
In your search path, only D:\tms\Products\registered\TMS WEB Core RSXE11\Component Library Source should be needed.
Do you always first perform a full uninstall of TMS WEB Core before you install a new version?
Yes.
Only new "HKCU ..BDS/19" via -r parameter helped me. I was unable to remove all errors in the registries
The TMS components fresh installation was then done using "Smart Setup".( in cca 4 minutes.)
TMS Web Core - this will be installed later.
I'm afraid that installing/uninstalling TMS Web Core brings those "///.." & Co. problems.
This probably happened after installing new items via "Smart Setup" and then experimenting with TMS Web Core.
Delphi stopped working for me with the error "system.pas or dcu not found".
It took many hours to resolve that issue.
An older version of the installer could sometimes leave a path with multiple backslashes but this was already fixed in the latest version of the installer.
Remove invalid paths like those with multiple backslashes from your library path and this should resolve the problem that Delphi cannot find system.pas
