Unable to "Upgrade" LiveMap

1
I run Live Map v2.7.1 on an IIS Server, runs fine but thought i would upgrade it to the latest.
When i try and install version 3.0 or 3.12 i click OK and nothing happens.
im using the latest TTMod 1.5.

Tried on IE/Chrome and Firefox, same result..
any ideas? i dont want to starts a new DB if possible.
