Easy Server Installation on Win/MacOSX?

[medips]

Can anyone share his/her experiences on server installation for  
lambda end-users?

What I want to evaluate is the possibility to build an installer for  
end users to install complete solution software themself very  
smoothly, i.e. without any problem. Then the installer will save on a  
specified location:
- my application (build with Revolution) and
- the Valentina server on one machine...
all in one click?

The end users will not be able to fix anything. Naturally this  
question is about evaluating if it is possible to sell a commercial  
product including the Valentina server to group of users without  
having to go physically on user' s office. And if this kind of e- 
business (downloading the application and self-install it) is risky  
(the user will face many problem and will abandon the application) or  
simply unrisky.

Thanks for any reply.
