Q1: Volvo 88890300 Vocom Software cannot be updated online. How to do after you update the software?

I bought VOLVO VOCOM on February 2015. I install the PTT 1.12 on XP system and run smoothly. But today, I have updated the Tt 1.12 software to the latest version but know I get the following error:

Communication unit minitor
Connected communication unit 88890020/88840133/88890300updated.
The software in the communication unit 88890020/88840133/88890300 must also be updated to be compatible.
See the Tech Tool help file for instructions on how to update the software.

A1:
This software and solution is only for customer who update the PTT1.12 software. If you do not update. Just use the PTT1.12 software comes with the CD on XP laptop.
