No

Hardware Configuration Information (be specific):

Bug Description:
"CurrentVersion" string for Java runtime environment not set in NT registry
when alternative version is installed.

Steps to Reproduce (be specific):

cases:
  - uninstall previous Merlin beta2 and install Merlin build 80,
  or
  - had 1.3.1x installed, uninstall Merlin build80

  both case, the "CurrentVersion" string for JDK and JRE are not set
  in registry. so having problem to lauch any runtime commands like java
  or javaw.

  if you reinstall without uninstall, then the "CurrentVersion" string
  will not be reset to empty string.

Also if you install 1.3.1x after Merlin build80, the "CurrentVersion string"
for JDK is 1.3, but 1.4 for JRE. It should be consistent and you will launch
1.4 java not 1.3 java.

workaround:
  patching the NT registry which is not acceptable. It should not require
  user to patch window's registry.
