Review Changed Support
Effective in version 10.1.1, Informatica dropped support for Data Analyzer, the Reporting Service, and the Reporting and Dashboards Service.
Effective in version 10.0, Informatica dropped support for Informatica services and Informatica Developer on 32-bit Windows. You cannot install Informatica services or the Developer tool on a machine with the 32-bit Windows operating system. You must migrate all nodes in the domain to a supported operating system before you perform the upgrade.
