Before installing the new version, it will uninstall the old version first.
Usually, your setting igconfig.xml file is stored at C:\Users\user_name\AppData\Roaming\ImageGlass, or check it in ImageGlass Settings > General > Configuration directory. You can back up igconfig.xml file if you want.
You can choose
- "Typical" to just install the ImageGlass files
- "Complete" to install ImageGlass files and the supported file formats (set as default viewer)
- "Custom" to choose what and where you want to install
