You may try the following steps:
Uninstall Switch, then delete 3 folders named "Switch" and 1 named "Components" from these locations:
**C:\Users\<username>\AppData\Roaming\NCH Software\Switch\
**C:\Program Files (x86)\NCH Software\Switch\
**C:\Program Files (x86)\NCH Software\Components
**C:\ProgramData\NCH Software\Switch\
**If you can't find any of the folders, just continue.
After that, restart your computer and reinstall the program.
Once done, restart your system one more time.
You will need to re-register the program using our current registration code. If you need assistance with the registration or installation, you can always contact NCH technical support team for assistance using the following link: https://www.nch.com.au/support/index.html
