I am trying to intstall SAC on Civil 3D 2011 and 2012 (both localized Italian version, 64bit on Win7/64bit).
On 2012 everything went fine.
On 2011, that has Update2 on it, it does not install (it says I require "Update 1 or later..")
I also tried to uninstall and reinstall Update1 and then Update2 (and Installing SAC at the end), but it did not work.
It seems it is a bug, or not?
I have the exact same issue. Also, it seems to recognise my Civil 3D 2011 English United Kingdom as a US version. Managed t o install on 2012 Eng UK 64bit, but I get a fatal exception when trying to import any PKT file created with SAC. A closer look at the installer indicates that the 2012 installation encouters a FE too.
Tried this on two workstations with the same results.
