AB Tutor v6. Got the Client installed fine by using the HTA MSI Editor as per their website, and pushed out by SCCM. Doing the same with the Tutor bit - but getting the following error...
Product: AB Tutor Control v6 -- Error 4121. Invalid Firewall process image path, or file not found: .
Machines are Window 7 Ent SP1. Nothing special about them really. Vanilla Setup.
