IBM Curam Word Integration Assistant – Compute JRE Home

We're currently upgrading to Curam 7.0.1. Most of our users have managed desktops and use Google Chrome as their browser of choice. We are aware if any of these users want to run the MS Word Integration they must, amongst other things, have run IBMCuramWordIntegrationAssistant.msi. This installer creates folders and copies files in their user profile - one of which is launchbridge.bat. This file references some environment variables:
userprofile - which is automatically specified by the OS
JRE_HOME - must be set manually to point to a Java installation

The problem is that our ministry pushes Java updates to our users' workstations about 3 times per year. With each update the old Java installation is removed when the new version is installed; and our users would have to update the JRE_HOME environment variable to keep MS Word Integration functioning. We've observed that launchbridge.bat has some lines that are commented out (with REM prefix) that compute the value for JRE_HOME. Enabling these commands (by removing the REM prefix) appears to work as expected - that is, JRE_HOME is set properly by launchbridge.bat without specifying it manually.

Would it be possible to get a version of IBMCuramWordIntegrationAssistant.msi that installs a version of launchbridge.bat that computes and sets JRE_HOME?

The contents of launchbridge.bat would be something like as follows:

@echo off
set JAVA_KEY="HKLM\Software\JavaSoft\Java Runtime Environment"
set JAVA_KEY_32="HKLM\Software\Wow6432Node\JavaSoft\Java Runtime Environment"
set JAVA_VERSION=
set JRE_HOME=

FOR /F "skip=2 tokens=3*" %%A IN ('REG QUERY %JAVA_KEY% /v CurrentVersion 2^>nul') DO (
set JAVA_VERSION=%%A
)

if "%JAVA_VERSION%" == "" (
rem Java version not found in 64-bit registry branch, check 32-bit
set KEY=%JAVA_KEY_32%
FOR /F "skip=2 tokens=3*" %%A IN ('REG QUERY %KEY% /v CurrentVersion 2^>nul') DO (
set JAVA_VERSION=%%A
)
) else (
set KEY=%JAVA_KEY%
)

FOR /F "skip=2 tokens=3-4*" %%A IN ('REG QUERY %KEY%\%JAVA_VERSION% /v JavaHome 2^>nul') DO (
set JRE_HOME=%%A %%B
)
cd %userprofile%\IBM\WordBridge
"%JRE_HOME%/bin/java.exe" -cp jacob.jar;commons-codec-1.5.jar;JSON4J_Apache.jar;chrome-native-host.jar curam.util.tools.fileedit.nativehost.NativeMessagingBridge
