Normally, LoadRunner is installed as One LR controller, this is where:

- Full setup of LR is installed
- Test scenario are created
- Load Test of runs
- Where all license(s) are installed

With 1 to 100's of LR load Generators(LGs):

- No licenses required
- These machines are used during load test to run the Vusers scripts
- Can be ''Full Setup'' installation of LoadRunner OR the Standalone LG software only
- Advantage of ''Full Setup'': The machines has all LR components installed (VuGen, LG, Analysis , etc.)
- LGs should not be used for creating/editing scripts; However, by have the LR Full setup installed you have the ability to verify that a script can connect/''touch'' the Application under test from that LG.
- Advantage of Standalone LG is the small software package to download
- Disadvantage of Standalone LG is no other LR standalone component can be installed on that machine

On all of the testers machines (their desktops/laptops/workstations):

- LoadRunner Full Setup on their local machines for creating script, editing, debugging and running small smoke test, proof of concept testing with the community
- Or, At a bare minimum, the testers need standalone VuGen, and standalone Analysis on their local machine
- They will still need physical access to the ''licensed'' Controller(s) to run full load tests

Happy Testing
