  • Install extension link for new version (Version 3.0.1952) doesn't work and returns 50* server error

  • URL for download new version (Version 3.0.1952) http://forums.iis.net/t/1226503.aspx?Microsoft+Application+Request+Routing+ARR+Version+3+0+1952+has+been+released

  • Hi,

    Can you comment on the reasons why removed a number of seemingly useful load balancing algorithms?


  • In contrast to what is said above, it does not work on Windows 10. "Microsoft Web Farm Framework -- IIS Version 7.0 or greater is required to install Microsoft Web Farm Framework." That's all I get, with or without PI.

  • Oops. The web framework message was from ARR 2.5 which I tried last. Nevertheless I get a similar message for the 3.0 version too, it only hangs at the URL Rewrite setup in that case. So different dependency, but same error.
