Using .net DLL

[Manish]

Hi,

I am using Installshield 12 and I want to use a DLL in it which i got
by building my Class Library project of C#.
I want to create a custom action which will use the method of that DLL.
I dont know why, it is giving error when it executes that custom
action.
It is giving error "Unknown Source". It can also be possible that i
might be using the dll in a wrong way as i am completely new to
Installshield.
Please tell me that is it possible to use that kind of DLL in
installshiled or I am doing something wrong.
Also please tell me that how mant types of dlls we can use in our
installshiled. I heard that we can not use .Net DLLs in installshield.

Please help me as i am badly stuck in it....

Thanks in advance.
