In attempt to fix this issue, you may try the steps below:

Uninstall Debut, then delete 3 folders named "Debut" and 1 named "Components" from these locations:
**C:\Users\<username>\AppData\Roaming\NCH Software\Debut\
**C:\Program Files (x86)\NCH Software\Debut\
**C:\Program Files (x86)\NCH Software\Components
**C:\ProgramData\NCH Software\Debut\
**If you can't find any of the folders, just continue. 

After that, restart your computer and reinstall (you may need to install the version that corresponds to the license you purchased)

Once done, restart your system one more time.
