I am trying to install exchange 2013 on Windows server 2008 R2 Enterprise SP1. I’ve installed all the required bundles as mentioned in this page. But, while installing exchange server 2013 i get the following error.

“the path to the language pack bundle was not found or reachable ”

Please help!

“the first Exchange installed smoothly and upgrade to CU10”

What are you using to install? You should be using the latest CU to install with, which is CU12. CU10 is already out of support.

FYI, there’s no need to install any earlier build of Exchange 2013 and then upgrade to the latest CU. You can always install directly with the latest CU.

3- I try first time with internal IP address but the mail is not delivered on external
