I downloaded Corel 15 trial verson but decided not to purchase. After trial I uninstalled the trial. Now when I use my pre-installed Corel 13 when I try to edit bitmap within Corel draw it open Windows 7 paint instead of Corel 13 Photo Paint. I tried doing a re-install REPAIR but I am having same issue. Any help would be much appreciated.
These instructions are for X4, but will probably work in X3 too.
Open photopaint and go to tools > options > filters > associate.
As far as I'm aware, the only association that you need is CPT but you may find it useful to add others if you would like other file types to open in photopaint.
