I Have been trying to up date from free version 10.1.101.000
for the past four days. ( vista pro op)

Each time I get
1)Toolnit failed
2)Error code 117 ( encountered error) (3aced2a)
then
3) Error 1603
Fatal error during installation

4)When I next start the computer the procedure starts again.

Any advice please????
