How can I build the components for 64 bits platform?

IW TMS IntraWeb Component Pack
1

I can use the TMS IntraWeb Components only in the Windows 32-bit platform. I need to use them in Windows 64-bit platform.
I tried to build them with the command:
msbuild IW16TMSDXE15UPD.dproj /p:platform=Win64
But I get the error message: Required package 'designide' not found.

IntraWeb components can be utilized to create 64-bit applications. Make sure that the 64-bit library path contains the directory where the TMS IntraWeb Component Pack sources are installed. Develop your application in 32-bit mode initially, then change the project target to 64-bit to compile it as a 64-bit application.
