32 bit Setup Instructions For Techstream
Please make sure your windows system is 32bit(Windows xp or 7), or refer to 64 bit installation instructions.

step1. install "TIS_Techstream_Setup.exe"


step2. After the installation, don't run the Techstream software.

2.1 Install the cable driver for whichever cable you're using such as MVCI (xhorse) driver or Mongoose cable driver.
2.2 If you ran the MVCI driver, this step will probably not be necessary, but other cable drivers may require you to change Techstream Function value. Now is the time to check the function setting by following these instructions: 

To activate any version of techstream, install whichever techstream .exe then open My Computer, C:\Program files\Toyota Diagnostics\Techstream\Env

open IT3System.ini file and scroll down to 

AVAILABLE FUNCTION SETTING

Switch TISFunction=1 to TISFunction=0


step3. Now run the Techstream software. Again in this case, the MVCI driver may bypass this, or if you opened Techstream before installing those drivers, these fields may show up. If they do:
3.1 Select any region.
3.2 Select the language you want,
3.3 Put anything you want in the registration fields then OK.

step4. Interface Select
4.1 Click the [Setup] menu, then click the [VIM Select], then select the cable you're using in the drop down list of "Interface Setup", then Click [OK]
