Is there any way to check whether Microsoft Java Virtual Machine is installed

[Erskine]

To verify whether JVM is installed, perform the following steps:

1. Start a command prompt--go to Start, Run and type

cmd.exe

2. Enter the Jview command by typing

C:\< jview

If the computer doesn't recognize the command, JVM isn't installed. When the computer does recognize the command, the JVM version will be displayed. For example, when I type the command in Step 2 on my computer, the following line indicates that JVM is installed:

Microsoft (R) Command-line Loader for Java Version 5.00.3809

6. Click Apply.

If you do not see the coffee cup icon in the Windows Control Panel, you do not have the latest version of the Sun JRE installed on your computer.

Hi,

If you are finding difficulties in manually removing the JVM machine installed on system, Try using JavaRa products from the Raproducts.

JavaRa is a simple tool that does a simple job: it removes old and redundant versions of the Java Runtime Environment (JRE)....

Hope this solve your problem.
