old photopaint won't work on win10

Hi! Going from a Win8 to Win10 new computer. Coreldraw 12 installs, but when I try to open Photo-Paint it seems yo be opening, then gives " referenced the memory could not be read" error message and close. I also have CD8, when I install that and try to open PP nothing happens, or rather in Task manager it appears as a background process but that's all. I asked Corel who say these are no longer supported and I should buy the new version for $500, which won't be happening. Tried compatibility modes without success. Any fix, or info on cheapest old version of photopaint which will run on win10? thx
