Thanks Igor - Good Question. It is in a Sony laptop with Intel HD Graphics 4000 fitted, (Portable to take to projector!) - a bit old
I ran the V10 .pte file in the old V9 which worked (it was originally updated from 9 to V10 but not changed much) and it produced an ,exe file which works ok so problem solved for the moment. The Video driver was updated earlier in year.
I have reverted to previous version of windows so now working again. Microsoft !!!!!!
Thanks
