2.) open 32 bit command prompt via C:\WINDOWS\SysWOW64

3.) Check java version 
C:\WINDOWS\SysWOW64>.\java -version
java version "1.6.0_10"
Java(TM) SE Runtime Environment (build 1.6.0_10-b427)

'.\java' is not recognized as an internal or external command,
operable program or batch file.

C:\WINDOWS\SysWOW64>ls -al java.exe

6.) Check java version on 64 bit command prompt. This is working fine.
C:\WINDOWS\system32>.\java -version

Java(TM) SE Runtime Environment (build 1.6.0_10-b427)
Java HotSpot(TM) 64-Bit Server VM (build 11.0-b13, mixed mode)

Expected Behavior:
64 bit and 32 bit JRE should not touch each othere system's directory.

Actual Behavior:
64 bit JRE is removing 32 bit java.exe from C:\WINDOWS\SysWOW64 diretory.
Comments
EVALUATION The problem is that the 64-bit MSI is removing files from the 32-bit system directory. We have entries in the RemoveFile table to remove java.exe from "SystemFolder", when it should be from "System64Folder". The fix is to make sure the 64 gets in there when we copy the RemoveFile table for 64-bit. Other files that I suspect are getting deleted are javaw.exe and javaws.exe.
