64 bit machines

64 bit machines and 64 bit JAVA

 

Most machines purchased in the last few years are going to be 64 bit capable and running 64 bit operating systems.  The problem is that most web browsers are still 32bit by default.  When you are prompted to download JAVA in most cases the resulting JAVA installation will be 32 bit. This means that your machine will only use a maximum of 1.3 gigabytes of memory even if you have 4, 8 or 16 gigbytes of memory in your machine.

This will cause the ResCarta Toolkit to install a 32 bit version for your machine with the same memory limitations.

To see what JAVA you have installed, open a command prompt/terminal  and type the following...

java -version

You should see something like ...

java version "1.8.0_131"
Java(TM) SE Runtime Environment (build 1.8.0_131-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.131-b11, mixed mode)

If your results do not include the  "64-Bit Server VM" statement then remove your currently installed JAVA and remove the ResCarta Toolkit if you have already installed it. (Don't worry we will keep the settings you already have).  Then go to 

https://java.com/en/download/manual.jsp

and select the Windows Offline (64-bit)  or Linux x64 RPM or Mac OS X  from the page.
