NIK 4 "already installed"

NIK 4 stopped working and said my trial was over (after having bought it in2021). I uninstalled, redownloaded and tried to re-install. Would not bring me to activation screen. DXO of no help. D/L’d the NIK Cleanup Tool, that wiped it off the system so it shows up nowhere, but when I try to install I get an error saying software is already installed. I really don’t want to pay $160 for NIK7. Any suggestions?

Hi and welcome to the user forum.

  • check → here … for compatibility

  • If Nik 4 should still work, contact DxO support and explain the circumstances
    (and prove that you paid for it …).

Your chart shows compatibilty with WIN 11. As stated, I have contaccted DXO and they are of no help…only to say they no longer support version 4. Also they have the record of my purchase.
