Good day members of DK

I had a HP 620 with windows xp pro on it and was using it everyday 100% with clone multidiag 1-2012 (19.09). Laptop broke and so bought a new HP Pavilion G6-2203si with windows 8 on it. Tried to load xp pro on it but no go because of encryption on the chipset. Managed to load windows 7 on it and vagcom works well but multidiag no go.

The multidiag software installs but will not connect to to any vehicles. When I try trouble shoot it it says drivers not digitally signed. I have heard that it needs 64 bit drivers so want to know if there are any members who can help me with drivers to get it working with windows 7?

Many thanks in advance
