Unfortunately no. The only trial a customer can start is IICS (Informatica cloud).
If you want to trail most software you would need to work with an Informatica account manager to get the correct keys.
If I may ask. What is the use case for PwC RT?
As mentioned by Scott.No trial license is available for PowerCenter or DataQuality or any other prodcut. Let su know for which product you are looking for licence. If you have avalid project with Informatica then you can raise a shipping request for the same.
