Change the user accounts I installed it on a laptop with vista an even though it was on an administration privelage and right clicking the file to edit it still it refused to save. Vista seems to have a problem with this and it would not let me change anything in the descr strat file I had to disable user accounts as it was driving me crackers for ages trying to figure out what was wrong . I used to have win 98 and in that you could change anything at will then I got XP you could only change if you selected the edit box when you right clicked the file but vista is just that bit more cumbersome. To change this just go to Settings then select User accounts Then just turn off user account control once off you can change anything hope this helps clear up confusion.
