Installing Java 32 bit on a 64 bit OS using a service

Has anyone had any success installing 32 bit Java on Win7 (64bit) using a Windows Service (Primasoft RunAsSvc)?

When trying to run, I am getting an 1619 error.

The 64 bit version works fine using this same method.

If I run the same script as a user, the 32bit installs succesfully.  

I have found some info on this website, but I have been unable to get it to work: https://harryjohnston.wordpress.com/2011/02/20/installing-32-bit-software-as-system-in-windows-7-x64/#comment-409

Here is the command I am running for the install:

;; 64bit
If @OSArch = "x64" then RunWait('C:\troyit\AutoInstaller\java\JavaInstall64.exe /s /L C:\TROYIT\AutoInstaller\java\JavaDeployLog-64.txt')

;; 32bit
RunWait('C:\troyit\AutoInstaller\java\JavaInstall32.exe /s /L C:\TROYIT\AutoInstaller\java\JavaDeployLog-32.txt')

Any help would be greatly appricated!

Thanks,
