I have both Designer pro 9 & 10. When I try to open an eps file it opens in DP9 instead of 10. I have tried to change the default program but it does not show DP10. I go to browse and select DP10 and DP9 opens the file, do I have to delete DP9 for this to work. In the registry it has ESP files to open with DesignerPro.exe, it does not say either 9 or 10. I want everything to open in DP10
