vb6 runtime isnt the problem. i get that error only in two cases.
1° is when i got the wil file im trying to export opened twice with the same or not the same app. i want to remember that if during the day u open twice a wil and get the error once u will have to restart the pc for not getting it anymore, its not enough just closing the second app which is reading the wil file.
2° sometimes i get also that error when i try to export a range of images in which there is a blank images bigger that 1kb or there is an image with some colours which mess lom image viewer up.. this is all i can say of that error. sorry
