Had to dig up an old thread. 
I was able to set this up as perscribed, but the issue I am having is now that I have changed the .vbs it uninstalls the verion I have installed I want to keep, 7_45.
Currently 7u45 is the latest and it will remove it (and successfully removes 6) and fail to (re)install 7_45.
Win7x64
I have downloaded the msi and cab files and running in the same dir.
Currently running it locally (tried admin as well) to test and gets a 1619 Java install error.
I can't manually install it at this point in my environment until I can get 7u45 to remain/be installed if not found.
Not super talented at coding, wondering how I could have changed the vbs script THAT much.
Any chance on an update for 7u45 DataSpike? 
(working on attaching log files if i can them to this device)
