How to minimize the installation setup?

Question

Hai,

In our inventory software the data base is sql and we use crystal report in the printing, so in clients Computer we need to install SQL Server and crystal report, dotnet frame work....etc

It takes a lot of time to install all these softwares and after that only we have to install and configure our software,

Is there any option to minimize the requirement to run the .net projects or is there any option to make a fast installation.

Please tell me,
Thanks in advance...
