Sorry, I should have been more explicit. Run the command from the Spine installation folder, eg:
cd C:\Program Files (x86)\Spine
java -jar launcher\launcher-full.jar
If Java is not in your command shell path, you'll need to specify the full path to it, eg:
cd C:\Program Files (x86)\Spine
"C:\Program Files (x86)\Java\jre7\bin\java" -jar launcher\launcher-full.jar
Note the quotes are needed because the path to java.exe
has spaces in it.
