To install the ITM ETL you have to insert the TEDW CD and then when is requested the kind of installation you want to perform (single machine, distributed, application only) you have to specify "application only" and then point to the directory where is the *.cfg of the ITM ETL.
You can install the ETL after the TEDW FixPack 02.
Anyway I would follow MY installation order and then install the ETLs.
By the way, do you know that you have to install at first the "general ETL" (AMX) and then the ETL for ITM for Operating Systems (AMY)?
More: if the ETL installation fails, that is you have a message telling there are "general errors", it's not told that the installation has failed!!!!!! If into the DB2 Datawarehouse Center there are the subject areas filled, probably the installation succeeded!
let me know...
