I upgraded my java version to 7 51 or something like that, anyway now that I have upgraded it, I can't run my servers; I just get this message in the command prompt: "C:\Users\Sean\Desktop\ServersNULLew folder>java -Xmx1024M -Xms1024M -jar minecraft_server.1.7.4.jar
'java' is not recognized as an internal or external command, operable program or batch file."
But before I upgraded I didn't get this message and it worked fine!
Please can someone tell me what I need to write or if I need to downgrade it? I would prefer not to degrade it though…
NOTE: I'm using the.jar version as the writing doesn't appear in the.exe file. This as recommended by someone on youtube and to uses the command code that I used, that DID WORK BEFORE.
