How do you work out what the default Cypress binary path of your install is?

Working in Windows, I'm getting the message
'Cypress' is not recognized as an internal or external command,
so presumably my installation is not finding the binary.

The question is how do you work out where the application is looking?

The command that would appear to provide that answer is
cypress verify
which gives me the following
> Cypress verify V Verified Cypress! D:\CypressEndToEndTesting\cypresscache\7.2.0\Cypress

based on that it made sense to set CYPRESS_RUN_BINARY to that value as follows
set CYPRESS_RUN_BINARY=D:\CypressEndToEndTesting\cypresscache\7.2.0\Cypress

However now I am getting
> Cypress verify Note: You have set the environment variable: CYPRESS_RUN_BINARY="D:\CypressEndToEndTesting\cypresscache\7.2.0\Cypress" This overrides the default Cypress binary path used. Could not run binary set by environment variable: CYPRESS_RUN_BINARY="D:\CypressEndToEndTesting\cypresscache\7.2.0\Cypress" Ensure the environment variable is a path to the Cypress binary, matching **/Cypress.exe

I can see that cypress.exe exists in "D:\CypressEndToEndTesting\cypresscache\7.2.0\Cypress" so what am I doing wrong?
