Installtion Step:
1. Install VIDA 2015A in Install\DVD\Vida_dvdheader\Main\setup.exe
2. After installation finished, DO NOT restart the laptop, run Patch VOLVO VIDA 2014D Patch 213064bit.exe directly in the root folder.
3. Restart laptop.

I didn't even uninstall my 2014D and it upgraded it.
However, reports of model support past 2017 seems like a stretch of the truth.
So, it will extend the life of Offline Vida to 2016 models.

VDASH can be used for later models which is in folder VDASH
