Okay, I've stumbled upon this thread whilst looking for a solution to 429. I copied the file from my office XP station to my laptop, and followed the registration instructions from your post to no avail. I'm on Mint 5 Gnome, which is built upon Ubuntu 8.04. I was thinking of combining all the solutions I've read: copy sscrun.dll and regv32.exe into /.wine/yadda yadda Has anyone come up with anything else to fix this? I only need to run this one program with Wine. I need to run Palo Alto's Marketing Plan Pro 9 and Business Plan Pro 8. I need it for my laptop as I go to meet with clients, and I refuse to go back to XP on this bad-boy. I am at least 3x faster with linux in place of XP. Thanks, Have an awesome day! Blake
