Did you get it working as I have the same problem
I use print house for poster ect and no only find it the best program for what I need but as I have used it for years I know it inside out so would like it to work on window 7
I have got it loaded working in windows 95 mode on windows 7 and can view files print and change things but as soon as I hit the save button the program crashes (Steve firstname.lastname@example.org)
I have not managed to get it to work on windows 7 either so have it working on Windows XP instead & would like to know if it works on anything else as I don't want to do without it when XP becomes "out of date". Meanwhile I have found "back door" to various times it tends to crash:
(1) when I'm trying to save it, I find if I use the left hand panel to go back to before I started to use the many options to work on it, until I can see the "Save" option on it, I then use the top bar and click "File" & "Save as" with success.
(2) When it sometimes crashes when I am in the middle of working on something, I make a point of saving it with a name in the early stages and then saving it often while I'm working on it so I don't lose too much. I hope this helps you as it has helped me.
