I tried to compile a java file and I got the "javac isn't recognized as an internal or external command" error. Last week it worked just fine.
The PATH variable seems to have been modified by something. I've tried changing it back to the correct address (C:\Program Files (x86)\Java\jdk1.7.0\bin), but it doesn't seem to reset. When I go into cmd and type
Echo %PATH%, I get the following message.
\bin;C:\WinAVR-20100110\utils\bin;C:\Program Files (x86)\Java\jre7\bin"
How should I change the PATH variable?
