I just got the vxdiag vcx se BMW diagnostic scanner and ISTA-P asks for an activation key. I followed your guide to paste the license key in ISTA-P text on desktop. But still not activated.
Solved. Change the computer date to the day after the current date.
For example, the current computer date is Nov. 21st, 2022. Change the computer time to Nov. 22nd, 2022.
