Hello,
Sorry to hear you are having trouble.
I just downloaded CursorFX 4.0. I uninstalled version 2.61, restarted the computer and then tried the install. The install fails with a decompression error 2026. Can't find a way to get the software to install.
I would like to have you re-download it and try again with that new installer, please.
