Hi @doolhoofd, I have few suggestions with software you referred.
- Equalizer APO website you linked isn’t original. This type of fake website provides malicious software. Original repo is here - Equalizer APO.
- Also Equalizer APO development was discontinued and dev suggests using Peace Equalizer.
- DeskFX is from NCH software, which has a reputation for providing buggy software. Their software are notorious for difficult to uninstall and making a mess in windows registry.
