Embarcadero caused a bug in C++Builder 11.2 patch 1 with library path configuration causing install problems of components for the Win64 target.
Embarcadero described the problem in this blog:
https://blogs.embarcadero.com/rad-studio-11-2-alexandria-patch-1-available/
The solution is explained in this blog:
Library Path Configuration
The RAD Studio 11.2 installation has an error in the configuration of the library path. Due to this configuration problem, linking with runtime packages fails, as reported in Quality Portal as RSP-39031 (Win64 build with runtime packages can’t find Win64 DCP files).
To address the issue you can alternatively:
Install the .reg file included in the patch download. We recommend you to follow this step only if you have a fresh install with no migrated settings and no third party component installed.
Use the IDE Tools Options dialog, select Language – Delphi – Library page and there the Windows 64-bit platform. Replace $(BDSCOMMONDIR)\Dcp
with $(BDSCOMMONDIR)\Dcp\$(Platform)
Open the Windows Registry Editor application (regedit), and make the following changes:
In the key –>
\Computer\HKEY_CURRENT_USER\Software\Embarcadero\BDS22.0\Library\Win64
change the “Search Path” value to
$(BDSLIB)\$(Platform)\release;$(BDSUSERDIR)\Imports\$(Platform);$(BDSUSERDIR)\Imports\$(Platform);$(BDS)\Imports;$(BDSCOMMONDIR)\Dcp\$(Platform);$(BDS)\include
In the key –>
\Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Embarcadero\BDS22.0\Library\Win64
change the “Search Path” value to $(BDSLIB)\$(Platform)\release;$(BDSUSERDIR)\Imports\$(Platform);$(BDSUSERDIR)\Imports\$(Platform);$(BDS)\Imports;$(BDSCOMMONDIR)\Dcp\$(Platform);$(BDS)\include
Please apply the fix Embarcadero suggests and then reinstall TMS VCL UI Pack.
