2.	Select Tools -> Option -> Environment Variables.
3.	From "System variables" list search for Path then click Add Override.
4.	Now add (LEAD)\Bin\CDLLVC10\Win32 in Variable value edit box.

 

Listed below are the steps used to install the VCL controls in Delphi 2006/2010/XE/XE2/XE3/XE4/XE5/XE6 and C++ Builder XE/XE3/XE4/XE5/XE6.

Delphi

1.	Start Delphi.
2.	On the Components menu, choose Install Packages.
3.	Click on the Design Packages Add button.
4.	Browse to the location of the Delphi LEAD VCL files. These are found in the LTVCL\Bin\CDLLVC10 directory. (LTVCL represents the directory in which you installed the LEADTOOLS VCL toolkit.)
5.	Select the control to add the following files and press OK:
	Delphi	Files
	2006	LTMain_2006.BPL, LTAdditional_2006.BPL, LTTwain_2006.BPL, etc. Please note that the LTMain_2006.BPL control must be on the system in order to install any of the other packages.
	2010	(LTMain_2010.BPL, LTAdditional_2010.BPL, LTTwain_2010.BPL, etc. Please note that the LTMain_2010.BPL control must be on the system in order to install any of the other packages.
	XE	LTMain_XE.BPL, LTAdditional_XE.BPL, LTTwain_XE.BPL, etc. Please note that the LTMain_XE.BPL control must be on the system in order to install any of the other packages.
	XE2	LTMain_XE2.BPL, LTAdditional_XE2.BPL, LTTwain_XE2.BPL, etc. Please note that the LTMain_XE2.BPL control must be on the system in order to install any of the other packages.
	XE3	LTMain_XE3.BPL, LTAdditional_XE3.BPL, LTTwain_XE3.BPL, etc. Please note that the LTMain_XE3.BPL control must be on the system in order to install any of the other packages.
	XE4	LTMain_XE4.BPL, LTAdditional_XE4.BPL, LTTwain_XE4.BPL, etc. Please note that the LTMain_XE4.BPL control must be on the system in order to install any of the other packages.
	XE5	LTMain_XE5.BPL, LTAdditional_XE5.BPL, LTTwain_XE5.BPL, etc. Please note that the LTMain_XE5.BPL control must be on the system in order to install any of the other packages.
	XE6	LTMain_XE6.BPL, LTAdditional_XE6.BPL, LTTwain_XE6.BPL, etc. Please note that the LTMain_XE6.BPL control must be on the system in order to install any of the other packages.
6.	To be able to compile with the control added, add the Delphi LEAD VCL files path (LTVCL\Bin\CDLLVC10) in the Project | Options | Directories dialog (Search Path).

 

C++ Builder

1.	Start C++ Builder.
2.	On the Component menu, choose Install Packages.
3.	Click on the Design Packages Add button.
4.	Browse to the location of the C++ Builder LEAD VCL files. These are found in the LTVCL\Bin\CDLLVC10 directory. (LTVCL represents the directory in which you installed the LEADTOOLS VCL toolkit.)
5.	Select the control to add the following files and press OK:
	C++ Builder	Files
	XE	LTMain_XE.BPL, LTAdditional_XE.BPL, LTTwain_XE.BPL, etc. Please note that the LTMain_XE.BPL control must be on the system in order to install any of the other packages.
	XE3	LTMain_XE3.BPL, LTAdditional_XE3.BPL, LTTwain_XE3.BPL, etc. Please note that the LTMain_XE3.BPL control must be on the system in order to install any of the other packages.
	XE4	LTMain_XE4.BPL, LTAdditional_XE4.BPL, LTTwain_XE4.BPL, etc. Please note that the LTMain_XE4.BPL control must be on the system in order to install any of the other packages.
	XE5	LTMain_XE5.BPL, LTAdditional_XE5.BPL, LTTwain_XE5.BPL, etc. Please note that the LTMain_XE5.BPL control must be on the system in order to install any of the other packages.
	XE6	LTMain_XE6.BPL, LTAdditional_XE6.BPL, LTTwain_XE6.BPL, etc. Please note that the LTMain_XE6.BPL control must be on the system in order to install any of the other packages.
6.	To be able to compile with the control added, add the C++ Builder LEAD VCL files path (LTVCL\Bin\CDLLVC10) in the Project | Options | Directories dialog (Search Path).
7.	In the Project menu, choose Add to Project and add the .hpp files. These can be found in the following directories, and must be added to use the controls in any application:
	C++ Builder	Directory
	XE	LTVCL\Include\VCL\XE
	XE3	LTVCL\Include\VCL\XE3
	XE4	LTVCL\Include\VCL\XE4
	XE5	LTVCL\Include\VCL\XE5
	XE6	LTVCL\Include\VCL\XE6

 

Note:	Since Borland is 32-bit application (DesignTime/RunTime) and 64-bit (RunTime only), make sure to add the below steps:
1.	Start Delphi.
2.	Select Tools -> Option. The Options dialog box will appear.
3.	From the left pan treeview, go to Environment Options -> Delphi Options -> Library.
4.	In Library Path select 64bit Platform, and add "(Embarcadero)\lib\win32\release", where Embarcadero is location of the installed embarcadero. For example, "c:\program files (x86)\embarcadero\rad studio\9.0\lib\win32\release" for XE2.
