In attempt to fix this issue, please try the steps below:
Uninstall PhotoPad, then delete 3 folders named "PhotoPad" and 1 named "Components" from these locations:
**C:\Users\<username>\AppData\Roaming\NCH Software\PhotoPad\
**C:\Program Files (x86)\NCH Software\PhotoPad\
**C:\Program Files (x86)\NCH Software\Components
**C:\ProgramData\NCH Software\PhotoPad\
**If you can't find any of the folders, just continue.
After that, restart your computer and reinstall the program. You may need to install the version that works with your license. Old versions can be found here: http://www.oldversiondownload.com/
Once done, restart your system one more time.
