In attempt to fix this issue, please 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 the program using this link: https://www.nchsoftware.com/capture/debutpsetup.exe
Once done, restart your system one more time.
Register the program and try again.
Before reinstalling the program, I recommend you to save your previous recordings to avoid losing them during the process.
