- **Do you need to have UFT installed on the load generators?**
**ANSWER:** No; however, you do need Standalone VuGen (or LoadRunner ''full setup'') on the UFT machine ( for Performance Center you need the UFT install on the PC host) see the LoadRunner /UFT integration
Support Matrix https://softwaresupport.softwaregrp.com/group/softwaresupport/search-result/-/facetsearch/document/KM01695362 page for the supported version.
- **How scalable are these types of Vusers, relative to TruClient or Web/HTTP vusers?**
**ANSWER:** There is no data available on the scalable or footprint for UFT API sciprts; however, since the UFT API does not have the GUI elements in the script it should be similar to that of the web(http/html).
- **Am I correct in assuming you don't need a GUI Vuser license to run these?**
**ANSWER:** Yes, don't need a GUI Vuser license bundle: However, you will need a Web 2.0 license bundle to run UFT-API Converted scripts
