how to update run-time to version 2.2?


I've installed vcvs2012_222.exe in win 8 dev environment as suggested by mf support to resolve an issue.

(1) How do i update the run-time? The current installation in our run-time environment was from cs2012_221.exe. If there's a 222 upgrade different from the vsvc upgrade above, please let me know where i can find this.

(2) Is the compatabilty add-pack now included in 2.2.2 i.e. do i need to install an add-pack upgrade separately in the dev and run-time environments?

Thank you,
