You can install the Informatica services in graphical mode on Windows.
When you run the Pre-Installation (i10Pi) System Check Tool before you perform the installation, the installer sets the values for certain fields, such as the database connection and domain port numbers, based on the information you entered during the system check.
On Windows, if you encounter problems when you run the install.bat file from the root directory, run the following file:
<installer files directory>\server\install.exe
Informatica recommends that you install the Informatica services and the PowerCenter Client in different install directories because If you install the Informatica services and the PowerCenter Client in the same install directory, the service binaries will be uninstalled when you uninstall the PowerCenter Client.
