well it look's like during the instalation, evpn keep's he's file's in *.msi archive. and what u need to get, it's from this file's specific file's for network driver & stuff like that
and where is the evpn configuration stuff ? use windows search

C:\Documents and Settings\user_name\aplication data\COMODO\EasyVPN
and no. if u dont have admin wright on pc, i think it's imposible to run it/add network connection/use it
