Zoo, there is an issue with launching Painter Photo Essentials on Windows 7. While not ideal, there is a work-around you can use to get the product launching, I have posted it in other threads on this forum, but here it is:
As a work-around to get the application launching on Win 7, can you please do the following:
Browse to wherever you installed PE4 to your hard drive, and in the Corel -> Corel Painter
Photo Essentials 4 folder, inside the "Resources" folder, create an
empty folder called "Color Profiles".
I hope that helps,
Jennifer
