[CR #535684] You cannot run ETL 4.8 concurrently with earlier versions of ETL, due to registry and resource conflicts. However, if you have Sybase ETL 4.1 or 4.2 installed on your machine, then installing ETL 4.8 on the same machine will prevent ETL 4.1 and 4.2 from starting.
Workaround: Do not install ETL 4.8 on the same machine that has earlier versions of ETL installed.
