ILMerge and SharePoint

Hello all,

I am extract data from multiple lists into an excel sheet using client object model in SharePoint 2010(Visual Studio .Net Managed Code).

I need to distribute a single .exe to multiple users who doesnt have any .net framework installed on their machines

I am using ILMerge tool to merge the DLLs (Microsoft.SharePoint.Client dll and Microsoft.SharePoint.Client.Runtime dll) to form a common exe file which is required to distribute.

Here are my questions

1)users doesn't like install .net on their machines, for that can I merge .Net Framework in ILMerge along with other DLLs?

2)In ILMerge If I select .Net Framework 4.0, will it work or I must select .Net 3.5?

Thanks
