Thanks for replying Sudhansu.
I tried using 14.00.02 and the silent installation went through. It runs in the background regardless of the switch used and takes a while to spool up so it was not obvious (actually crashed my machine with multiple concurrent silent install attempts the first time), but it does work.
I got the uninstall to work as well. By default the PRIORTOVERSION is set to 14.00.00.00 so it must be set appropriately to uninstall higher prior versions. Again this was a bit of work since TTU actually consists of multiple versions so even using 14.00.04 was not working (I ended up using 14.10.00 which works fine).

Hope this helps others.
