Installing development setup on 64 bit Windows OS.

Hello Everyone,


I want to setup a development environment on computer on which 64 bit Windows OS is installed. I am getting the error


'Windows cannot find 'javaw'. Make sure you typed the name correctly, and then try again.


At first glance I thought that the Java has not been installed properly, but I think Java is installed properly. I have checked the environment variable "path" and it is set properly. I tested by iving the path of both, the bin folder in JDK as well as bin folder in JRE. But still it is giving the same error.


Do I need to install two different Java SE i.e. for x86 and x64? where x86 is for 32 bit and x64 is for 64 bit OS.


Are there two different JDK available for 64 bit Windows OS? i.e. 32 bit JDK for 64 bit OS and 64 bit JDK for 64 bit OS?


Please guide me to set up an environment. Any help would be greatly appreciated.


Thanks and Regards.

Re: Installing development setup on 64 bit Windows OS.

The BlackBerry development tools require the 32 bit JDK, which can be installed on 64 bit versions of Windows.


Once you have that installed, point your PATH and JAVA_HOME environments to the 32 bit JDK installation.

Re: Installing development setup on 64 bit Windows OS.

I have installed Eclipse Plugin on Windows 7-64 bit

(in my case as VM on OSX)

here are the steps in detail:



as Mark says: most important is the use of 32-bit JDK - of course you can have both (32-bit and 64-bit) JDK on your machine if PATH and JAVA_HOME are pointing to 32-bit

Re: Installing development setup on 64 bit Windows OS.

hehe...i had this problem last year when I upgraded to a 64bit machine.  I ended up returning the PC cuz it didnt work with JDE.


I wish i had known this problem before Smiley Happy
