Installing Siebel Developer, Mobile and Siebel Tools client: Prerequisite Checks fails (Doc ID 1321056.1)
Looks like you might have better success with SNAC 9.0.
Thank you. But it was not helpful for my problem...
If I will use SNAC 9.0 am I need to change ODBC properties for server "SBA..."?
It work`s with SNAC 9.0... Probably because when install Web client 220.127.116.11 you need previously install base web client 18.104.22.168 (it can work only with SNAC 9.0).
