The AOS "AOSHostName" cannot be reached, Setup cacnot continue. Verify that you entered the correct server information and that the AOS service is running. AX 2012

Hi,

one of my team was installing AOS report extension for AX 2012 RTM and got the below error message and screen (right)
"The AOS "AOSHostName" cannot be reached, Setup cacnot continue. Verify that you entered the correct server information and that the AOS service is running."

ideally the folder location screen should come and then AOS server details screen should come after below screen, but it throws directly to the right side screen and with error message.

























Observation
 I have checked all the point and did not leave any stones untouched, like n/w, ports, services running, SQL etc.
all were very fine.
finally I have noticed that the installer team was using was AX 2012 R2, but the AOS installed was RTM. so the old dll (RTM) was not able to communicate to AX 2012 R2, hence it was unable to communicate.

Though it was stupid to use R2 for report extension installation, but it was provided by the client and team did not think to chk the version.

hope this will help some one, though STUPID.
