    I have installed Versions 17 or 18 32bit programs on Windows 7 Pro at least ten times.
    Everything goes great communicating over the cable and the program reads the VIN and populates the live data like it should, but nothing I have been able to do will make the magical UTILITY button appear so I can bleed the frakking brakes.
    Wiped the drive and did a fresh install of Win7 Pro - no Change.
    Tried changing the order of installation - no change in behavior.
    Anyone else had this problem?

    You need to download a copy of Techstream from another source – and keep trying until you find one that has the utility button. Try an older version like V9.x.xx or V10.xx.x. You don't need the latest version for the Gen 2 Prius.

    If all else fails, there is a ready-to-run version of Techstream v12 in a Virtual Machine (VM) that runs in VirtualBox. VirtualBox is a free open-source application supported by Oracle that you can run on any version of Windows, macOS, or Linux.

    I agree that you need to install an older version of Techstream. Try version 12 to 14. I think they will work on windows 7 32-bit.

    Use Windos 10 64bit and get v18 TS.

    Also a good tip is to change baud of the usb device.

    Its default at 9600 kbps, that’s 1988 speed. Check device manager and manipulate this upwards until TS fails with communication… This value effects everything. Go for at least 115000..
