GMX-PhotoPainter didn't work on any of the four computers I had, two of which had Windows 7 Home Premium and two had Windows XP. After numerous unsuccessful attempts to install it, I paid attention to the license agreement, which says the following: This program and all accompanying files, data and materials are distributed as is, without any warranty, either express or implied. The user must assume all risk from using the program. The disclaimer of warranty is an essential part of this agreement. It goes like this.
