Instead of Sandboxie, another alternative would be to install it in a virtual machine using VirtualBox (which is free) or some other virtual machine software. You can then download a free 90-day evaluation version of Windows 10 (or 8.1 or 7) from Microsoft's website (in the section for developers), with Windows already preinstalled into a VM that you can import into VirtualBox. Then just install TC v20 inside of it. Both 32-bit and 64-bit software and OSes will run in there.
