VXDIAG engineer replied:

Before this step you have to install java while installing will ask you to go with j2534 driver or skip.

Don’t skip you have to be sure fully installed.

You have to use internet explorer don’t use google chrome or normal windows browser.

Open explorer in admin mode to be able to update the j2534 wrapper and problem solved.  Update  j2534 driver to the latest version. 

Any step have problem go complete out and start again
