Only Windows 10 x64 has been tested, previous versions (XP, 7, 8) are NOT guaranteed to work and support will be limited.
For Sprite Viewing
Terraria must be installed or the data files must be available, normally
64bit: Program Files (x86)\Steam\steamapps\common\Terraria\content

Steam and Gog versions of Terraria normally work. However, you might be able to get other types to work with the steps below.
If you don't have Terraria installed on the PC you are using there will be no sprite visualization, but the application should still work if you meet the other requirements.
If you don't have Terraria installed but have a copy of Terraria/Content e.g. shared network drive, virtual machine, USB drive, etc., you can uncomment and edit <AltC> in settings.xml to point to your custom Terraria/Content location.
NOTE: Remove the <!-- and --> to uncomment the line
NOT compatible with any mod files or TConfig modified worlds
ONLY supports textures with a Steam copy of Terraria installed
If you don't have Terraria installed but have access to Terraria/Content (e.g. shared network drive, USB), you can point to it by uncommenting and editing <AltC> in settings.xml
