I do the .msi and I run it on the client. It works !

I have just a few questions.

1. The msi it contains the whole class (I thought the the client doens't need to register anything.) ?
2. It is the same if I register the class on ther client (with regsvr32) or it is different ?
3. Do I need to be the Administrator on the client machine ?
4. What are exactly the permission I have to give on the server related to the com+ and to the folder where the dll is saved ?
5. Do I have to give special permission about com+ on the client machine ?

Thanks a lot !
