what bitness is your Operating system 32 or 64 ?
If its windows you usually can tell -> computer - (right click) -> properties -> windows 64 bit yatta yatta

for Java - go to a command line and type

C:\Users\grperry\Desktop\ENV>java -version
java version "1.7.0_21"
Java(TM) SE Runtime Environment (build 1.7.0_21-b11)
Java HotSpot(TM) 64-Bit Server VM (build 23.21-b01, mixed mode)
A common problem is installing 32 bit Java on a 64 bit machine .. or some other mis match 

checked the machine  its a 32 bit, as for the java was alittle unsure tried the cmd line  made  altered the user name  from yours but  came back the system cannot find the path specified , but am almost sure i installed java 8, 32bit  but am reinstalling java this morning

reinstalled the java but again the cmd line doesnt work am thinking am not  putting it in the right place , but the auto installer  doing the work.
