Hello,
In attempt to fix this issue, please try the steps below:
Uninstall MixPad, then delete 3 folders named "MixPad" and 1 named "Components" from these locations:
**C:\Users\<username>\AppData\Roaming\NCH Software\MixPad\
**C:\Program Files (x86)\NCH Software\MixPad\
**C:\Program Files (x86)\NCH Software\Components
**C:\ProgramData\NCH Software\MixPad\
**If you can't find any of the folders, just continue.
After that, restart your computer and reinstall the program using this link: https://www.nch.com.au/mixpad/mpsetup.exe
Once done, restart your system one more time and try again.
Regards.
