Here is another link I found in research, for future reference:
beaunoz;9974138 said:I have an old version of Techstream with no key registration required. I run it on an old IBM laptop with Windows XP 32 bit. I downloaded from here: Techstream TIS VCI Installation Guide (64-bit OS) Including All Software Needed! - Toyota GR86, 86, FR-S and Subaru BRZ Forum - FT86CLUB
The link includes a publicly accessible DropBox link to the software as well. https://www.dropbox.com/sh/mztf3wrqa...i5qy1xpoa?dl=0
It works on all my Lexus vehicles (2006 SC430, 2009 LX570, 2003 RX300, 2001 IS300). Customize options and all.
Also I'm not sure what changed between my version v9.30.xxx and v12.0.xxx.
