Can HPALM Explorer v12.21 work without IE?

Hi All,

We are in a process of decommissioning IE from our organization.

We are currently using HPALM Explorer v12.21 for connecting to on-premise HP ALM server.

Just wanted to confirm if the HPALM Explorer  v12.21 is using no components of IE (active x etc). So that after removing IE from the laptops, HPALM explorer still works.

Can anyone help?
