im not expert in .net field, but isnt .net something like java? so really this pe exe isnt exe its just like dos info in PE file, this program cant be run under dos, so same here with pe, you need .net enviroment like java. so only way is wait for olly2 or debug .net tools that start this exe, or maybe look on .net exe specification and it maybe has additional structure like tls in execryptor
