DO NOT UPDATE KEYSHOT!!
I done the update thorugh Keyshot, and now I have a trial version of Keyshot! It is not recognizing my Solid Edge keyshot license that is installed with ST7
I updated mine and it still works fine as KeyShot Solid Edge although I updated it by downloading the update, not using the Check for Updates link in Help.
I'm running ST7 on my machine, but it's ST6 for production still...
