Install Issue Painter 12 Trial on Win 7

Have an install issue - not the other see thru screen install issue on this forum - I can see the license agreement ok but I cannot accept the license agreement - clicking next goes nowhere. I have seen this issue on the internet but no resolution - would like to evaluate this software for purchase.

Any help would be appreciated.

Many thanks in advance

Must be a win 7 problem - loaded right up on a virtual XP partition - not the first program I have had to run like this but performance will take a hit.
