Sub Tasks

Description
On a windows machine, perform the following steps:

1) Install JRE 1.4.2_10
2) Install JRE 1.5.0_05 or Mustang
3) Uninstall JRE 1.4.2_10

The HKLM\Software\JavaSoft\Java Runtime Environment\1.4 is still there after uninstallation of JRE 1.4.2_10. 

This problem existed since JRE 1.4.2 but manifested differently there; the values of the sub-keys under the above mentioned key are different.

EVALUATION

The problem has existed in all versions of JRE 1.4.

A check needs to be added for the following dangling keys for 1.4 remaining in the registry, if no 1.4 version is installed.
HKLM\Software\JavaSoft\Java Runtime Environment\1.4

When there is no other versions of JRE installed the code works fine, but if there is another version of 5 or 6 installed the issue is seen.

So added check to remove the key
