Yes, I just recently did it with the instructions above. When I clicked on the link for the previous version it was not the same as listed, but I went with it because I assumed that is what my printer used. So I believe whatever is in your temp files is your last version, but I had to use these instructions to downgrade so I might not be the most reliable advise. Good Luck! It is worth it. My printer worked immediately with the previous ink cartridges.
