Poser 11’s 11.1 update is now available, via your Smith Micro Download Manager.
If you run a 64-bit instead of a 32-bit install of Poser 11, then you need to make sure to un-check the 32-bit check-box when the installer runs. Otherwise it may look for both 64-bit and 32-bit installs of Poser, and may then get confused when it can’t find the 32-bit.
If you don’t yet have 11, the Smith Micro site currently has a load of discounts on Poser 11. Including on upgrades from older versions.
